I had a bit of figuring to do. For one thing, while we Americans think our way of doing things is always best, the European metric system is actually far better than our own multi-unit way, even the conservative British are adopting it, and oddly enough an imperial gallon is a better measure than our American gallon because one imperial gallon weighs exactly ten pounds of fresh water. It didn't take much figuring to see that a drum would hold four hundred and twenty pounds of water.
There was some other reckoning to be done and I persevered, even to cutting shapes out of paper with a rusty pair of scissors. At last I stretched, put Kironji's pen safely back in a drawer, took a hopeful but useless look in the cooler and set off down to the lakeside on foot. It was only a short distance and I used the walk to do some more thinking. I went straight down to look at the pontoon once again.
It was a rickety enough contraption, just a few empty oil drums for flotation with a rough log platform bolted. on top. It was very weathered and had obviously stood the test of time, but it was as stable as a spinning top just about to lose speed and I wouldn't have cared to cross Central Park Lake on it.
I yelled for anybody and Bob Pitman responded.
'Bob,' I said, 'go round up a couple of people for me, will you? I want Kemp, Hammond, and Geoff Wingstead. Oh, and Mick McGrath. Ask them to meet me here.'
'Will do,' he said and ambled off. When they had all arrived I found that Zimmerman had got wind of the conference and had made himself part of it, though without his Russian mate. I looked around at them and drew a deep breath.
'I have a nutty idea,' I started.
This drew a couple of ribald comments and I waited until they died down before I carried on. 'It's crazy and dangerous, but it just might work. We have to do something to get ourselves out of this fix. You gave me the idea, Ben. You and Mick.'
'We did?' Hammond asked.
'Yes. I want us to build a raft.'
'I know I mentioned that but you shot that idea down in flames. You had a point too.'
'I've developed your idea. We don't use this thing as a basis, we build our own. I've done some figuring on paper and I think it will work. The trouble is that the lake isn't made of paper.' I filled in for the benefit of the others. 'Ben suggested that if we towed the landing stage it could form a raft on which we could get people over to Manzu. The pontoon isn't big or stable enough and we'd need transport on the far shore. But I think I've worked something out.'
'Build a bigger raft?' asked Wingstead.
'How could you power it?'
'What do we make it of?'
'What do you think this is, a navy shipyard?'
I held up my hand. 'Hold it. Give me a chance and I'll explain.' There were two phases to my scheme and I thought it wiser to introduce them one at a time, so I concentrated on the concept of the raft first. 'To start with, every one of these drums in the compound, when empty, has a flotation value of four hundred pounds, and there are hundreds of them. We won't need more than say one hundred for my plan to work.'
'Sounds idiotic to me,' said Kemp. 'A hundred of these drums won't make a raft big enough to take anything anywhere.' I knew he was trying to visualize the rig floating across the lake on a bed of oil drums and failing, and had indeed done that myself.
'Building a raft is the first part of my plan. And it'll do to go on with, unless someone has a better one. We can't stay here indefinitely.'
'It sounds like you have a pretty big job lined up,' Wingstead said. He didn't sound encouraging. 'Let's hear it.'
'Think about the raft. To make it we need material and muscle. And brains, I guess. We've got the brains between us and there's a hell of a lot of suitable raw material lying about. As for the muscle, that's how the pyramids were built, and the Great Wall of China. God knows we've got enough of that.'
The Nyalans?' Hammond asked. He was beginning to kindle with excitement. I wanted them all to feel that way.
'We'll need a work force. The women to plait lianas to make a lot of cordage, and some of the men to cart stuff about. I've got the basic blueprints right here.' I held up the pad of paper.
Zimmerman and Hammond looked ready for any challenge. Kemp had a stubborn set to his jaw and I knew that he was thinking about the rig to the usual exclusion of everything else, and ready to oppose any plan that didn't involve saving it.
Geoff Wingstead was oddly lacklustre, which disappointed me. I'd hoped to enrol his enthusiasm first of all, and wondered why he was hanging fire. McGrath had said nothing and was listening intently in the background. With the odd, unwanted rapport that I sometimes felt between us I knew he was aware that I had something tougher yet to propose, and he was waiting for it.
Hammond said, 'How do we persuade the Nyalans to cooperate? We can't pay them.'
'Sister Ursula gave me the answer to that. We can take as many of them across to Manzu as want to go. When the war's over they'll probably drift back again, but right now they're as threatened as we are. I think they'll help us.'
Kemp had been drawing in the sand, and now he said, 'Look, Neil, this is ridiculous. To build a raft big enough to take maybe a couple of hundred people is crazy enough, but to take vehicles across on them is beyond belief. Good God, each tractor weighs forty tons. And how do we embark and disembark them?'
I said, 'You're thinking the wrong way. I agree with you, and I've already rejected that idea. We don't build a raft to get people to Manzu.' It was time to drop the bombshell.
'What? Then what's all this about?'
I said, 'We're going to use it to capture the ferry.'
They stared at me in total silence. McGrath's face warmed into a broad grin of appreciation.
Wingstead said at last, 'You're out of your mind, Neil.'
'OK, what the hell do we do? Sit here and eat ants until the war goes away? We have to do something. Any immunity as foreigners and civilians we might have had was shattered when we met up with Maksa's force. We played soldiers then. And I have a bad feeling about this war; if the Government forces were going to win they'd have done so by now. The rebels are gaining strength and if they take over they aren't going to be exactly lenient.'
Wingstead said, 'You're right. It just seems so far-fetched.'
'Not at all,' said McGrath. 'It's a lovely idea, Mannix. Lovely. How did I give you the idea, if I might ask?'
'You mentioned fire ships,' I said shortly. I needed him desperately but I was damned if I could make myself at ease with him. 'We're going to attack the ferry from the water, the one thing they won't expect.'
I had him with me, naturally. I thought I had Hammond too. He was fully aware of the danger but absorbed by the technical challenge. Kemp might disapprove but couldn't resist putting his mind to the problem.
Hammond said, 'I think at this stage you want to keep this rather quiet, don't you, Mister Mannix?'
'Yes. Why?'
'I'd like Bert Proctor in on it from the start. He's got a good head, and I've worked with him on projects so often — '
I said, 'Yes, of course. Go get him.'
He went off at the double and Wingstead smiled. 'They really are quite a team, you know.' I was still worried about his lack of enthusiasm. He was the kingpin of the team and they looked to him for direction.
Proctor, grave and attentive as always, listened as I recapped. He calmly accepted the idea of Wyvern Transport men turning into privateers, and I understood why Hammond wanted him.
I showed them my idea for building the raft. I hadn't yet calculated the load but I reckoned on as many men as we could muster, at least one or maybe two trucks and whatever we could develop in the way of weapons — a formidable prospect. They were dubious but fascinated and the engineers among them could see the theoretical possibilities. We had to build a raft before considering the rest of the plan.
To Kemp I said, 'Basil, I've got an idea about the rig too. I know how important it is. We'll talk about that later.' This was a sop; I had no ideas about the rig but I couldn't afford to let him know it.
McGrath asked, 'How many men do you think we'll have?'
I said, 'All of Sadiq's men, that's twenty-three. We can't conscript our crew but I don't think anybody will want to be left out. I make that sixteen. Thirty-nine in all.'
'Say thirty-five, allowing for accidents,' said McGrath.
'Fair enough.'
'What did Sadiq have to say about the ferry?'
'They have a guard detachment there. Exactly how many we don't know, but it doesn't sound formidable. If we come out of the dark yelling at them they'll probably scatter like autumn leaves.'
Faces brightened. It didn't sound quite so bad put that way.
McGrath said, 'We'd need much more accurate information than that, Mannix.'
'Oh, I agree. By the way, I haven't spoken to Sadiq yet, but we will soon. I want to propose an expedition, using Sam Kironji's boat. You, McGrath, Geoff, Sadiq and myself. It won't take any more. Down river by night.'
Wingstead said, 'Oh my God, Neil, I don't think we should do that.'
I was dumbfounded. 'What the hell's the matter with you, Geoff? I'm depending most of all on you. For God's sake stop being such a damned pessimist.'
I'd never let fly at an executive in front of his men before. But it was vital to keep morale high and a waverer at the top of the command line could ruin all our plans. He made a strangely listless gesture and said, 'I'm sorry, Neil. Of course I'm with you. Just tired, I guess.'
Zimmerman broke into the embarrassed silence. 'I don't think Geoff should go anyway, Neil. He's got enough on his plate already. Let me come instead.'
I was relieved. Damn it, I wanted Wingstead with me, and yet in his present mood he might be a liability. I wished I knew what was eating him.
'Suppose we succeeded, took the ferry. What then?' Hammond asked. 'Wouldn't their main force get to know about it?'
'Very likely, but they're at Fort Pirie and we'd silence radios and prevent getaways,' I said. 'The only thing we have to pray for is that the ferry is operative, and from what Kironji told me it's been in regular use recently so it ought to be.'
Then what?' Wingstead asked.
'We bring up the rig and get all the invalids on board the ferry, cram it full of people and shoot it across to Manzu. When it comes back we pile on as many vehicles as it can take, trucks for preference, and the last of the people. Once in Manzu it's a doddle. Get to Batanda, alert the authorities and send back transport for the stragglers. I bet they've got cold beer there.'
They chewed on this for a while. I had painted a rosy picture and I knew they wouldn't entirely fall for it, but it was important to see potential success.
Hammond stood up and rubbed out the sketch marks in the sand with his foot. 'Right — how do we start?' he asked practically.
Wingstead looked up, absurdly startled. His face was pale under its tan and I wondered fleetingly if he was simply afraid. But he hadn't been afraid back in the warehouse at Makara.
'I don't know,' he said uncertainly. 'I'd like to think about it a bit, before we start anything. It's just too — '
The hesitation, the slack face, were totally unfamiliar. Doubt began to wipe away the tentative enthusiasm I had roused in the others. Wingstead had cut his teeth on engineering problems such as this and he was deeply concerned for the safety of his men. I had expected him to back me all the way.
The problem solved itself. He stood up suddenly, shaking his head almost in bewilderment, took a dozen paces away from us and collapsed in the dust.
We leapt up to race over to him.
'Go and get a doctor!' Kemp barked and Proctor ran to obey. Gently Kemp cradled Wingstead whose face had gone as grey as putty, sweat-soaked and lolling. We stood around in shocked silence until Dr Kat and Dr Marriot arrived.
After a few minutes the surgeon stood up and to my amazement he looked quite relieved. 'Please send for a stretcher,' he said courteously, but there was one already waiting, and willing hands to carry Wingstead to the mobile hospital. Dr Marriot went with him, but Dr Kat stayed behind.
'I should have seen this coming,' he said. 'But you may set your minds at rest, gentlemen. Mister Wingstead will be perfectly all right. He is not dangerously ill.'
'What the hell is it then?' I asked.
'Overstrain, overwork, on top of the injuries he suffered in the plane crash. He should have been made to take things more easily. Tell me, did you notice anything wrong yourselves?'
I said, feeling sick with anger at myself, 'Yes, I did. I've seen him losing his drive, his energy. And I damned well kept pushing at him, like a fool. I'm sorry — '
Kemp cut me off abruptly.
'Don't say that. I saw it too and I know him better than anyone else here. We must have been crazy to let him go on like that. Will he really be all right?'
'All he needs is sleep, rest, good nourishment. We can't do too much about the last but I assure you I won't let him get up too soon this time. I might tell you that I'm very relieved in one respect. I have been afraid of fever — cholera, typhoid — any number of scourges that might strike. When I heard that Mister Wingstead had collapsed I thought it was the first such manifestation. That it is not is a matter of considerable relief.'
The Doctor's report on Wingstead was circulated, and the concern that had run through the convoy camp like a brush fire died down.
I found Hammond. 'I want to talk to all the crew later this evening. The medical staff too. We'll tell them the whole plan. It's risky, but we can't ask people to work in ignorance.'
Then I went to find Sam Kironji.
'Sam, what's in that little hut inside the compound?' I asked him.
He looked at me suspiciously. He'd already found the compound gate unlocked and Harry Zimmerman and two others counting empty drums, much to his disgust. 'Why you want to know?'
I clung to my patience. 'Sam, just tell me.'
There was nothing much in it. The hut held a miscellany of broken tools, cordage, a few other stores that might be useful, and junk of all sorts. It was where Sam put the things he tidied away from everywhere else.
I made a space in the middle of it, had Kironji's desk brought in, and established it as my headquarters. The roadside cabin was too far from the camp and too exposed. Some wag removed a Pirelli calendar from the cabin wall and hung it in the hut, and when Kironji saw this I think it hurt him most of all.
'Stealers! Now you take my women,' he said tragically.
'Only to look at, same as you. You'll get them back, I promise. Thank you for the desk and the chair, Sam.'
He flapped his hand at me. 'Take everything. I not care no more. Mister Obukwe, he fire me.'
Hammond was listening with amusement. 'Never mind, Sam. If he does I'll hire you instead,' I said and hustled him outside. I sat down and Hammond perched on the end of the desk. We each had a pad of paper in front of us.
'Right, Ben. This is what I've got in mind.'
I began to sketch on the pad. I still have those sketches; they're no masterpieces of the draughtsman's art, but they're worth the whole Tate Gallery to me.
Take an empty drum and stand it up. Place around it, in close contact, six more drums, making damn sure their caps are all screwed home firmly. Build an eight-sided wooden framework for them, top, bottom and six sides, thus making a hexagon. No need to fill the sides solidly, just enough to hold the drums together like putting them in a cage. This I called the 'A' hexagon, which was to be the basic component of the raft. It had the virtue of needing no holes drilled into the drums, which would waste time and effort and risk leaks.
How much weight would an 'A' hexagon support?
We got our answer soon enough. While we were talking Sandy Bing reported breathlessly to the office. 'Mister Mannix? I got forty-three and a half gallons into a drum.' He was soaking wet and seemed to have enjoyed the exercise.
'Thanks, Sandy. Go and see how many empties Harry Zimmerman has found, please.' Zimmerman and his team were getting very greasy out in the compound.
The drums were forty-two gallons nominal but they were never filled to brimming and that extra space came in handy now. We figured that the natural buoyancy of the wooden cage would go some way to compensate for the weight of the steel drums, and Bing had just handed me another few pounds of flotation to play about with. We decided that my 'A' hexagon should support a weight of 3,000 pounds: one and a half tons.
But there wouldn't be much standing room. And a floating platform about six by five feet would be distinctly unstable. So my next lot of figures concerned the natural development upwards.
All this would take a little time to produce but it shouldn't be too difficult. Testing the finished product as a floating proposition would be interesting, and finding a way to push it along would stretch a few minds, but I didn't really doubt that it could be done. And the final result, weird of shape and design, was going to win no prizes for elegance. I jiggled with a list of required materials; some of them were going to be hard to find if not impossible. All in all, I couldn't see why on earth I was so confident that the plan would work.
'We have to go up a stage, Ben,' I said, still sketching. 'Look at this.'
The hexagon is a very useful shape, ask any honey bee, but I doubt if it has been used much in naval architecture.
'Start off assuming we've built an 'A'-gon,' I told Ben. That was how new words came into a language, I guess, though I didn't think this one would last long enough to qualify for Webster's Dictionary. Ben caught on and grinned in appreciation. 'Here's what comes next.'
Take an 'A'-gon and float it in shallow water so that a man could stand on the bottom and still handle equipment. Float another six 'A'-gons round it and fasten together the hexagons of the outer ring. There is no need to fasten the inner one because, like the first drum, it is totally surrounded and pressed in from all sides.
The result is a 'B' hexagon, a 'B'-gon in our new nomenclature, with a positive buoyancy of ten and a half tons, enough to carry over a hundred people or a medium sized truck. We decided to make two of them, which is why we needed a hundred drums.
Hammond was impressed and fascinated. 'How do we make the cages?' he asked.
'We'll have to find timber and cut pieces to the exact size,' I said. 'That won't be too difficult. I'm more concerned about finding planking to deck it, otherwise it'll be unsafe to walk on.
Nyalan women make good cordage, and We can lash the 'A'-gon frames together, which will save nails. But I'm worried about the fastening of the larger 'B'-gons. Rope and fibre won't help us there. We need steel cable.'
'I've got some,' he offered, a shade reluctantly.
'I don't want to have to use that yet. We'll figure out something else.'
I stood up. 'It's only four o'clock and I need some exercise. There's two hours of daylight yet. Let's go build us an 'A'-gon.'
We were just leaving the office when Bing arrived back.
'Mister Zimmerman says they've only found sixty-seven drums.' he said.
At the compound we found Zimmerman, Kirilenko and Derek Grafton looking mucky with old oil and somewhat bad-tempered. It appeared that there were not many empty drums. Kironji seldom got them back, and these had not been placed neatly away from the full drums but stood all over the place. Here Kironji's normal tidiness had deserted him, to our detriment. It didn't help that neither Grafton nor Kirilenko knew why they had to find empty drums, and of the two only the Russian was equable about taking unexplained orders.
I commiserated with them and sent them off for a breather, after we'd rolled eight or nine drums down to the lake shore. Zimmerman stayed with us. Hammond left in search of Kironji, to get the workshop unlocked; he would cut some timber frameworks and we decided to use rope, which we, knew was available, for the prototype 'A'-gon.
'I don't see how we're going to find enough empties,' Zimmerman grumbled.
'Ever hear about the guy who went into a store to buy some eggs? There was a sign up saying "Cracked Eggs Half Price", so he asked them to crack him a dozen eggs.'
Zimmerman smiled weakly.
'You mean empty out full drums?'
'Why not? To start with we'll fill every fuel tank we can with either gas or diesel, and all our spare jerrycans too. If there are still not enough drums we'll dig a big pit somewhere well away from the camp and ditch the stuff. And put up a "No Smoking" notice.'
He realized I wasn't joking and his jaw dropped. I suppose that as an oil man he was more used to getting the stuff out of the earth than to putting it back in. Then we were interrupted by Sam Kironji in his usual state of high indignation.
'You cut trees! You use my saw. You never stop make trouble.'
I looked enquiringly at Sandy Bing who had raced in behind him. 'Yes, Mister Mannix. Mister Hammond found a chain saw in the workshop. But it won't be good for long.. The teeth are nearly worn out and there's no replacement.'
Kironji shook his head sadly. 'You use my saw, you welcome. But you cut tree, you get in big trouble with Mister Nyama.'
'Who's he, Sam?'
'Everybody know Mister Nyama. Big Government tree man. He cut many tree here, with big machine.'
I said, 'Are you telling us that there's a government logging camp near here?'
'Sure.'
'Well where, for God's sake?'
Sam pointed along the lake. 'One, two mile. They use our road.'
I recalled that the road led on past the compound, but I hadn't given any thought as to where it went. A bad oversight on my part.
'Chain saws,' Zimmerman was saying, his voice rising to a chant of ecstasy, 'Axes, felling axes, trimming axes, scrub cutters.'
'Fantastic. Get off there right away. We've got enough drums to be going on with. Take some men, some of Sadiq's if you have to. I'll clear it with him. And Harry, plunder away; we'll make everything good some time. Break in if you have to. My bet is that there'll be nobody there anyhow.'
Zimmerman went off at a run and Kironji said dolefully, 'You steal from Government, you steal from anybody.' Hammond rejoiced at the good news and had some himself. 'Found an oxyacetylene welding kit in there with a few bottles. And a three-and-a-half inch Myford lathe that'll come in handy.'
'Bit small, isn't it?'
'I'll find a use for it. There's another outboard engine, too, and some other useful bits and pieces.'
'Take them,' said Kironji hysterically. 'No need you steal. I give.'
I chuckled. When he saw us pouring his precious gasolene into a hole in the ground he'd be a broken man. 'Come on, let's build our 'A'-gon.'
It took six of us nearly two hours to build the prototype 'A'-gon but then we were inventing as we went along. From the middle distance the Nyalans watched us and wondered. Our people came to watch and make comments. At last we wrestled it down to the water and to our relief it floated, if a trifle lopsidedly. We dragged it ashore again as the light was fading and Bing arrived to say that a meal was ready. I felt tired but surprisingly contented. This had been a fruitful day. I was careful not to dwell on the possible outcome of my plans.
After an unsatisfying meal everybody gathered round, and between us as Hammond and I explained the basics of the scheme. We said little about the military side of the operation and discouraged questions. We concentrated on the more immediate goal, the building of the 'B'-gons.
Grafton was sceptical, possibly because he'd had first-hand experience of the labour involved.
'It took you two hours to make that thing. How many do you need?'
'Fourteen for two 'B'-gons. Possibly more.'
He looked appalled. 'It'll take days at that rate.'
'Ever hear about Henry Ford's biggest invention?'
'The Model T?'
'No, bigger than that. The assembly line.'
Hammond said at once. 'Ford didn't invent that. The Royal Navy had one going in Chatham in seventeen ninety-five for making ships' blocks.'
'I think the Egyptian wall paintings show something like an assembly line,' put in Atheridge.
'We won't be chauvinistic about it,' I said. 'But that's what we're going to do. We build simple jigs, stakes driven into the sand will do, one at each corner to give the shape. Then the teams move along the rows. That's the difference between this line and those in Cowley or Chicago. Each man goes along doing just one job. They lay down the bottom planking, put the drums on top, drop the side members between the stakes and make them fast. Then they put on a top and do likewise.'
They listened intently, and then Antoine Dufour spoke up. His English was good but heavily accented.
'I have worked in such a place. I think it is better you take the Japanese model, piecework is no good here. You will have too many people moving about, getting confused perhaps. You want teams each in one place.'
It took very little rethinking to see that he was right, and I said so.
'Great going, Antoine. It will be better that way. Each team builds one 'A'-gon from the bottom up, complete. Another team to go along doling out material. Another one rolling the drums to them. And a couple of really strong teams to shift the finished 'A'-gons to the water, probably towing them on mats. We've got rubber matting in the trucks.'
I looked at Dufour. 'You say you've had some experience at this. How would you like to be in charge of the work teams, you and Dan?'
He considered and then nodded. 'Yes. I will do it.'
His matter-of-fact acceptance of the feasibility of the programme did a lot to encourage the others. Questions and ideas flew about, with me taking notes. At last I held up a hand for silence.
'Enough to go on with. Now let's hear from Doctor Kat.'
The Doctor gave us a brief report on Lang and on Wingstead, who was sleeping soundly and would be none the worse as long as he was restrained for a few days. 'Sister Mary is much better, and taking care of Mister Wingstead is the perfect job for her. She will keep him quiet.'
I hadn't seen much of the senior nun but if she was anything like Sister Ursula there was no doubt that Geoff Wingstead would shut up and obey orders.
Of the other invalids, he said that as fast as they got one person on their feet so another would go down with exhaustion, sickness or accident. The rickety thatched wards were as busy as ever.
I turned to Harry Zimmerman.
'Harry's got some good news he's been saving,' I said.
'We found a logging camp,' he reported cheerfully. 'We brought back two loads of equipment, in their trucks. Chain saws, axes, hammers, nails and screws, a whole lot of stuff like that. The big power saws are still there but they work.'
'But you did even better than that, didn't you?' I prompted.
'Yeah. Planks,' he breathed happily.
'We'll be bringing in a load in the morning. That means our decking is sorted out, and that's a big problem solved. And we can get all the struts for the cages cut to exact measurements in no time.' The assembly responded with more enthusiasm than one might have thought possible, given how weary they all were.
'It's amazing,' said Dr Marriot. 'I saw your 'A'-gon. Such a flimsy contraption.'
'So is an eggshell flimsy, but they've taken one tied in a bag outside a submarine four hundred feet deep and it didn't break. The 'A'-gon's strength lies in its stress factors.'
She said, 'It's your stress factors we have to think about,' and got a laugh. Morale was improving.
The meeting over, we dispersed without any discussion about the proposed attack on the ferry for which all this was merely the prologue, and I was grateful. Those who were to be my fellow travellers in the boat stayed on to talk. We decided to move out by first light and return upriver in time to get cracking on the coming day's work. Sadiq had been briefed and while not exactly enthusiastic he had agreed to come with us, to see the enemy for himself.
Later I lay back looking at the dark shape of the rig looming over us, a grotesque shape lit with the barest minimum of light. I wondered what the hell we were going to do with it. I had enough thinking to keep me awake all night long.
But when I hit the sack I didn't know a thing until I felt Hammond gently awakening me, three hours before dawn.
