CHAPTER 2 How to Swim Fifty Meters Underwater Without Dying Confidence

Ice floated in the water outside of my hotel window as I zipped my dry suit shut.

I’d been staring out of the window off and on since we’d spotted the bloody sea lion carcass on the shore that morning. The sea lion’s body had a huge gash in its side, and the ice around it was bloodred. A killer whale did it, or that is what the locals told us. I would have appreciated the scene more, but in less than an hour, my SEAL teammates and I were about to get in the same water to plant a bomb on a U.S. Navy ship.

I took some solace in the fact that at least the killer whale had a full stomach.

I was a brand-new SEAL, having graduated BUD/S just nine months earlier, and it was cool to be back in Alaska training. The scenario was pretty simple. My SEAL platoon got tapped to play the OPFOR—military jargon for “opposing force,” or the bad guys. It was our job to attack an amphibious assault ship moored at the pier in Ketchikan, Alaska. We had to sneak in close enough to the ship to set tracking devices. Some of the ship’s crew as well as a small contingent of Army soldiers would be guarding the ship and surrounding areas. Their task was to defend against a threat like us.

There was a foot of snow on the pier and the water temperature was hovering just above freezing as we prepared. I smeared black paint on my face and squeezed all of my warm clothes under my dry suit.

One of my teammates knocked on my door, and I grabbed the rest of my gear and headed out. We met in the parking lot of our hotel and the four of us on the OPFOR assault team—all dressed in dry suits and painted faces—climbed into the back of a U-Haul truck. We were the brand-new guys in the platoon.

If the dark, cold water and the seal-eating killer whales weren’t scary enough, we also had to worry about Flipper, a killer dolphin stalking us from the deep.

I’m not kidding.

The Navy has bottlenose dolphins trained to attack divers. The dolphins were part of the U.S. Navy Marine Mammal Program, which trained both dolphins and sea lions to detect mines and protect harbors and ships. Both the United States and Russia spent millions on these kinds of training programs, and the dolphins were used in combat during the Gulf War and in operations off the coast of Iraq. The Russian program was disbanded in the late 1990s, and word was their killer dolphins were sold to Iran.

The Navy had flown three dolphins up to Alaska from San Diego in heated tanks so that they could hunt us. One dolphin was stationed in a cage at each end of the ship that was our target, and the third was free-swimming. The dolphins in the cages were trained to use their sonar to detect divers. When they heard us coming, the dolphins were supposed to surface and ring a bell attached to the cage. The dolphin handlers would then call in via radio that the dolphin had heard something, and the patrol boats would come looking for us.

When the free-swimming dolphin spotted a swimmer, it attacked, forcing the diver to the surface. We had to deal with a giant dolphin swimming full speed in the dark water repeatedly bashing us with its nose until we swam to the surface. It’s no fun heading into icy, pitch-black water in the dead of night under any conditions, but the constant possibility of a giant dolphin ramming you at full speed added a little anxiety to the mission.

A few hours before we hit the water, two of my teammates in plain clothes had made their way along a nearby dock with a pair of dive tanks. When they got near the ship, they opened the valves at the top of the tanks, allowing just enough air to escape to make bubbles. My teammates tied the tanks together and dropped them over the side of the pier, lashing the anchor line to the rail before they walked away. The bubbles were white noise underwater to cover our approach.

With the tanks in the water, we left the hotel and headed toward the river that ran from the town to the channel. We bounced along the rutted roads of Ketchikan in the back of the U-Haul. I could hear our equipment rattle as tanks banged against the wall. No one spoke. I was nervous. I wasn’t the best swimmer, and navigating underwater in pitch-black darkness while hunted by a killer dolphin wasn’t going to be easy. But it wasn’t the dolphins or the killer whale that scared me the most. It was the swim to the ship.

Much of the town was built on a wooden dock where the ship was moored. The conventional approach would have been to swim out in the main channel, which is where the dolphins were stationed. We had decided to sneak in from under the immense pier network. If we came in from the river, the large stanchions holding the pier together would mask our movement. But that also meant we’d be swimming in complete darkness through a maze of pylons and debris. We couldn’t use flashlights for fear of attracting the dolphins below or the guards patrolling the dock above us. We would have to silently feel our way from pylon to pylon. This swim was going to be all by touch, as we worked our way through the water.

The truck coasted to a stop and we could hear the driver—another teammate—talking to a security guard. My heart rate kicked up and we held our collective breath. If they searched the truck, the mission was done. We sat for only a few seconds, likely because of traffic backed up at the checkpoint, but it was a very long few seconds. At last I could hear the engine roar as we headed to the bank of the creek.

I felt the truck slow and then stop. The driver cut the engine and seconds later threw open the back door. I climbed out of the truck with the other three divers and trudged through the snow to the water.

We got into pairs and attached a line to each other so no one would get lost. I would never be more than four feet apart from my swim buddy. We waded into the water. I took two long and slow deep breaths, put in my regulator, and slipped into the creek. With our goggles on and dive rigs ready to go, we gave each other a quick thumbs-up and began submerging ourselves in the frigid water. I had to stifle a gasp as the ice-cold water washed over my head and face. In seconds it was pitch-black.

“I hate diving,” I thought.

I was nervous. This was one of my first missions—it was training, but we were in an uncontrolled environment and the dangers were real—and I wasn’t completely comfortable in the water. I knew being a SEAL meant underwater operations, but I dreaded them. The water portion of BUD/S was hard for me. The long runs and push-ups during BUD/S never worried me, but the water tests did. I wasn’t a surfer. I wasn’t really a swimmer. I had never done a lot of swimming as a kid in Alaska.

I can remember my dad challenged me once when I was almost a teenager to swim across the river in front of our house. The current pushed against me as I slowly swam. By the time I reached the far bank, I was a quarter of a mile downriver from where I’d started. That was the farthest I’d swum before I started training for BUD/S. When it came time to pass the fifty-meter underwater swim during BUD/S, I had the same nervous feeling as I had getting ready to dive under the dock in Alaska.

The fifty-meter underwater swim is one of the first pass-or-fail tests during BUD/S. I remember it was a sunny day in June, the clouds having burned away to reveal a blue sky. The pool was across from the BUD/S training area on Naval Base Coronado, which sits across the bay from San Diego.

My BUD/S class ran over to the pool in the morning. We’d already spent hours in the cold surf doing flutter kicks and running for miles in the sand. We all knew the test was coming, and there was a nervous energy up and down the ranks. We crowded on one side of the pool in our tan shorts, shirtless and barefoot, and listened to the safety brief.

“If you want to stay in this training, you’re going to have to do this swim,” the instructor told us as we huddled on the deck. “The key is to stay as relaxed as you can.”

The swim wasn’t timed. Swim fifty meters in the twelve-foot-deep pool—down and back in one breath. Safety swimmers were positioned above and below us as we swam. Doctors and an ambulance waited poolside in case of emergency.

The test was simple, on paper. But that was before the instructors took away any advantages. No diving off the wall. We had to step out far enough to do a front flip underwater, so once you started toward the far end of the pool you had no forward momentum.

The underwater swim was part of the first phase of BUD/S, which includes a grueling five-and-a-half-day stretch called Hell Week. During Hell Week, each candidate sleeps only about four total hours but runs more than two hundred miles and does physical training for more than twenty hours per day.

BUD/S is all about training your mind and body to achieve more than you think possible. It is the first test in a SEAL’s training and career. The SEAL motto, “The only easy day was yesterday,” was about to become very clear to us.

I don’t think I realized it at the time, but BUD/S is a series of building blocks starting with the fifty-meter swim and Hell Week in the first phase, followed by dive training in the second phase, and then firearms and explosives training in the final phase. Basically, you start with baby steps and end up doing the things that can kill you if not handled correctly. You have to pass each one to keep going. Fail once and you wash out.

I knew, coming from Alaska, that swimming was going to be my weakest skill. My SEAL buddy in college taught me the breaststroke and the sidestroke, which is all I needed. And for one semester, I worked out with my college club team. But of all the tests in BUD/S, this one worried me. I knew it was all or nothing. I knew no matter how tired, nervous, or scared I was, I couldn’t let doubt creep into my head. I had to make it.

After the safety briefing, we sat in lines—nut to butt, as we say—in our tan shorts. Over my shoulder, I could hear splashes as my classmates jumped into the pool. The night before, guys had been full of tips and advice. We’d talked about trying to stay deep. I didn’t want to be a foot underwater, because I might be tempted to poke my head up. I had decided to try to stay at six or seven feet.

There was no talking as I waited for my name to be called. A few minutes before I stepped to the edge of the pool, I took two deep breaths. I wanted to slow everything down in my mind in an attempt to relax and focus.

“This is easy,” I told myself as I walked to the edge of the pool. “All the instructors did it. It’s not impossible. Chill out.”

When it was my turn to go, I stepped feetfirst into the pool and disappeared under the surface. I pushed my head down and kicked my legs over into a flip. I could feel the water surge up my nose, forcing me to blow out some of my last breath. I was uncomfortable from the start.

I pushed my hands up and using the breaststroke started toward the far end of the pool. It looked more than twenty-five meters away. I knew the test was a battle of distance, not time. I didn’t hurry. Instead, I concentrated on slow, deliberate strokes. There is a saying, “Slow is smooth and smooth is fast.” I was living proof as I glided below the surface.

I felt good physically, but I couldn’t stop my mind from thinking about how far away the wall looked. At the bottom of the pool, I spotted one of the instructors. He had a regulator in his mouth connected to a scuba tank. I watched as he tracked us from the bottom, ready to spring up and rescue one of us if we started to drown.

Above me, another instructor with a scuba mask and snorkel kept pace. He looked like a predator ready to dive after his prey.

The whole swim takes only forty seconds to a minute, but it felt a lot longer. My lungs kept reminding me I needed air and my mind was begging me to surface. As I reached the wall, I spun around and set my legs to push with all my might. It felt good to have some momentum heading back to where I started.

By now, the burning in my lungs was impossible to ignore. I knew I’d be “chicken necking” soon. That is the first step before you pass out. Think of it as a gag reflex. I could feel my head start to bob as my body tried to force me to breathe. The first feelings of panic started to tingle, but I quickly pushed them deeper into my mind. Instead, I focused on my slow, deliberate stroke, as the wall grew larger and larger.

“Just keep swimming,” I pleaded with myself. “Keep swimming.”

But I couldn’t stop the gasping. It wasn’t mental. It was my body in revolt. My lungs were on fire, threatening to come out of my chest. My mind started to panic and my focus began to wane. It isn’t natural to deny your body air. We’re hardwired to survive, and we need air to do it.

But I fought to get control of my mind. I focused on the ever-growing far wall. I committed to staying underwater. I refused to give up. This was the first real test. If I couldn’t do this in a clean, heated pool in sunny San Diego, what was I going to do in the North Atlantic during a storm?

The chicken necking eventually stopped, and with each stroke, I got closer to the wall. But I could also feel myself losing consciousness. My vision blurred around the edges. With each stroke, the darkness started to crowd my vision. Like a fog, the shadow started in my peripheral vision and I knew in a few seconds I might pass out.

I had to be near the wall. I reached out to touch it. Rough hands grabbed me under my arms. The instructors pulled me out of the water like a trophy fish. I flopped down on the pool deck and took a deep breath. I could feel my lungs draw in deep, and my body relaxed. I took several more deep breaths and then tried to get up.

“Stay down,” I heard one of the instructors bark at me.

I rested my head back on the warm deck. It’s rare for instructors in BUD/S to let you rest, and I was going to take full advantage. One by one my classmates finished. I watched the instructors throw the limp body of one of my classmates up onto the deck. He was out cold. After a few quick breaths, he gagged and coughed his way back to consciousness. The minute he did, he looked at the nearest instructor.

“Did I make it?”

The fact that seconds before, he was unconscious seemed like a minor detail. I understood because, like him, I didn’t want to fail. Failure was almost worse than death.

“Stay down,” an instructor said. “Relax.”

I was enjoying the sun on my back. It was paradise, for a few seconds. The instructors saw I was fine.

“Get the fuck up and head over to the pass line. You did it.” Those were great words to hear.

No one who makes it through BUD/S ever thought he’d fail. BUD/S is relentless and forced me to dig deep. I never doubted myself. I knew I’d pass. I think people mistake a SEAL’s confidence for arrogance. But after the fifty-meter swim, Hell Week, and dive training, where the instructors do their best to drown you, we know our limits and we know how to push well beyond them. During BUD/S I overcame dozens of obstacles that looked insurmountable at the time, and that gave me the confidence to know I could do it again.

But bobbing in the near-freezing river in Alaska, I had to work hard to muster that confidence. I wasn’t sure I could do this, but tied to my buddy and nearing the opening to the pier, I didn’t have a lot of choice.

It took only a few minutes before I couldn’t feel my face. We let the current push us toward the harbor. At its widest the Ketchikan Creek is only about twenty feet and only five feet deep, so we bobbed at the surface until we crossed the first bridge. We were using Draeger diving rigs, which use pure oxygen. There are no bubbles when we exhale, keeping us much quieter.

As we passed under the bridge, I could hear the snow crunching under the tires of the cars above. Somewhere above us, I knew guards patrolled. Spotlights from the ship crisscrossed the black water, looking for us.

The water got deeper under the bridge, and before we crossed underneath we dipped below the surface. It was difficult to see anything in the ink-black water. We swam to the right bank and started searching for an opening in the pylons that led under the pier.

I could feel the tug of the rope on my belt as my partner swam nearby. I found the edge of the first pylon, figured out the direction I needed to move, and plunged farther into the darkness. I held my hand out in front and slowly kicked my way past the first pylon. My hand brushed against it, sinking into the green algae clinging to the wood.

Any minute, I expected to be pummeled by the dolphin’s nose as it forced me to the surface. We crept more than swam as we picked our way through the maze of algae-covered pylons.

Debris littered the bottom. Several times my flippers brushed against metal or trash. Each time we got close to a pylon, we had to be careful of jagged nails. If we tore a hole in our dry suit it would be more than just cold; it could be fatal because water would fill the suit, making it impossible to surface. Drowning was a real possibility.

I knew my swim buddy was near because of the tension in the rope. It was so dark that I remember lifting my hand and putting it directly in front of my face. I couldn’t see anything. Besides the dark, we had to deal with the cold. Beyond the cold we had to worry about the dolphins, and besides the dolphins we had to worry about getting lost under a town built on pylons. It felt claustrophobic.

I could barely make out the reading on the glowing green compass on my wrist. I tried to keep a steady pace on the right heading, but every few feet I had to dodge around a pylon. It took us an hour to get to the ship. I was relieved when we finally reached the ship’s hull. It’s surprising when you’re swimming in the pitch black with your hands in front of you and you swim into the massive hull of a warship. It makes you feel so small. I quickly snapped out of congratulating myself for making it when I realized we were only half done. In order to complete the mission, we had to place the device and make it back to our truck without being detected.

From below the water line, the ship was massive. I ran my gloved hand over the rough steel and waited for my partner to remove the collapsible pole strapped to my back. The pole was like the one used to replace letters on a sign at a gas station. The head of the pole had magnets and rollers on it. I pulled one of two dummy bomb devices out of a bag on my belt and attached it to the head. I ran my hand over the wheels on the head to make sure they rolled freely and tapped my partner on the shoulder. He placed the rollers on the skin of the ship and slowly slid the training device up the side, letting it roll along the hull until it was in place. The device attached to the ship by magnets. As it broke the water line, we got the device’s magnets too close to the skin of the ship. I felt the device grab hold of the hull of the ship with a “thunk.” I pushed the pole back and forth until the bomb came free. I worried the noise of the magnet pulling the device toward the ship had given away our position.

I closed my eyes and tried to focus. I was doing it all by feel only. I couldn’t see anything anyway, and my mind was playing tricks on me. I kept seeing movement in the black water. Each time, my heart raced, waiting to feel a dolphin or killer whale barreling into my side at full speed.

Inch by inch we slid the device up the hull of the ship until it reached the three-foot line.

After we got the second device in place, my partner helped me collapse the pole. He lashed it in place on my back and we started the long, cold swim back to where the truck had dropped us off. It was a total relief when we swam back under the bridge. This time, there were fewer cars passing along the bridge and from a light posted by the road I could make out that it had begun to snow again. I was tired and my nerves were frazzled after working in complete darkness for well over two hours. But in my head I knew the only relief was up the creek and into the back of a U-Haul truck.

My legs shook when I stood up onshore. Someone threw a blanket over me and helped me drag my gear to the truck. I could barely talk because my face was still numb. Minutes later I was back in the dark as the truck rumbled back to the hotel. I couldn’t feel my face, but I know I had a smile.

We were a bunch of new guys fresh from BUD/S and we’d just completed the mission. It was a training mission, but diving under the pier wasn’t easy. We’d been on other training missions before, but this time our officer trusted us to plan and execute the mission on our own and we succeeded. It felt good to be trusted.

“Anybody see the dolphin?” a teammate said.

“Nope,” I said. “I couldn’t see shit.”

“Every time I felt the water move, I tensed up, ready to get the shit beat out of me,” my partner said.

It turns out the free-swimming dolphin had spotted the smorgasbord of fish in the harbor and taken off. The two dolphins in the cages—used to the warmer San Diego Bay—stayed near the surface and every ten minutes rang the bell to get a fish. The dolphins didn’t want to be in the cold water any more than we did. The steady noise from the tanks masked our approach from the dolphins, and nobody had seen or heard us plant the training devices. We had actually pulled off the mission.

I was nervous the entire time. But I used the exact same focus to get through this mission as I did the fifty-meter underwater swim back in BUD/S. My confidence was growing, but it wasn’t a hundred percent yet. When I got into combat a few years later, I couldn’t focus on the negative—the dark, the cold water, killer dolphins. There can be zero thought of failure or quitting once the fighting starts. Looking back now, I can see that my confidence grew stronger with every experience, in training and in combat. The sense of purpose I had learned from my parents had gotten me started, and once my confidence kicked in, I was on my way to becoming an effective operator and an asset to the team.

Of course, I still had a lot to learn.
