Cryptonomicon (62 page)

The next day, the front had covered the sky with low blue-grey clouds from horizon to horizon. U-691 was far out of sight of land. Even so, Bischoff had Holz, his chief engineer, take her up to periscope depth first. Bischoff scanned the horizon meticulously. Satisfied that they were perfectly alone, he had Holz bring her to the surface. They fired up the diesels and pointed the boat east. Their mission was finished, their boat was damaged, it was time to go home.

Two hours later a flying boat bellied down through the cloud layer and dropped a skinny black egg on them. Bischoff was up on the bridge, enjoying some fresh air, and had the presence of mind to scream something about evasive action into the speaking tube. Metzger, the helmsman, instantly took it hard to starboard. The bomb plunged into the water exactly where the deck of U-691 would have been.

It continued in that vein until they got far away from land. When they finally limped back to their base at Lorient, Bischoff told this story to his superiors in tones of superstitious awe, when they finally broke the news to him that the enemy had this new thing called radar.

Bischoff studied it and read the intelligence reports: the Allies were even putting the shit on airplanes now! It could see your periscope!

His U-boat is no longer a rat in a dark cellar. Now it is a wingless horsefly dragging itself across an immaculate tablecloth in the streaming light of the afternoon sun.

Dönitz, bless him, is trying to build new U-boats that can stay submerged all the time. But he has to beg for every ton of steel and for the services of every engineer. In the meantime there is this stopgap measure, the Schnorkel, which is just plumbing: a pipe that sticks up out of the water and enables you to run on diesel power, just beneath the surface. Even the Schnorkel will show up on radar, but less brilliantly. Every time U-691 surfaces for more than an hour, Holz is up there working on the Schnorkel, welding new bits on, grinding old bits off, wrapping it in rubber or some other stuff that he hopes will absorb the radar. The engineers who installed the Schnorkel in Lorient six months ago wouldn’t recognize it now because it has evolved, like shrews evolving into tigers. If Bischoff can just get U-691 back to a safe port, others can learn from Holz’s innovations, and the few U-boats that haven’t been sunk can derive some benefit from the experiment.

He snaps out of it. This must be how officers die, and get their men killed: they spend more time reviewing the past than planning for the future. It is nothing short of masturbation for Bischoff to be thinking about all of this. He must concentrate.

He doesn’t have to worry so much about being sunk by Germans. As soon as he sent Dönitz the message threatening to broadcast the information about the gold, Dönitz retracted his general order to sink U-691. But there is the possibility that some ship might have received the first order but missed the second one, so he still has to watch himself.

Big deal. There is hardly any German Navy left to sink him anyway. He can worry about being sunk by the Allies instead. They will be intently irritated when they figure out that he has been shadowing this convoy for two whole days. Bischoff is pretty irritated himself; it is a fast convoy that protects itself by zigzagging, and if U-691 does not zigzag in perfect unison with the ship above it, it will either be crushed by her, or blunder out of her shadow and be noticed. This has put quite a strain on skipper and crew, and quite a drain on the boat’s supply of benzedrine. But they’ve covered five hundred miles! Soon, fatal Biscay will be be
hind them, Brittany will be off to starboard, and Bischoff will have a choice: hang a right into the English Channel, which would be suicidal; head north between Britain and Ireland, which would be suicidal; or veer to the west around Ireland, which would be suicidal.

Of course there’s always France, which is friendly territory, but it is a siren whose allure must be sternly resisted. It’s not enough for Bischoff just to run the U-boat aground on a godforsaken beach somewhere; he wants to get the thing back to a proper base. But the skies above the proper bases are infested with Catalinas, illuminating the sea with the satanic light of their radars. It is much cleverer to make them think that he’s headed for France, and then head for a German port instead.

Or at least it seemed that way two days ago. Now the complexities of the plan are weighing on him.

The shadow of the ship above them suddenly seems much longer and deeper. This means either that the earth’s rotation has just sped up tremendously, moving the sun around to a different angle, or that the ship has veered towards them. “Hard to starboard,” Bischoff says quietly. His voice travels down a pipe to the man who controls the rudder. “Anything on the radio?”

“Nothing,” says the Funkmaat. That’s weird; usually when the ships are zigzagging, they coordinate it on the radio. Bischoff spins the periscope around and gets a load of the transport, still trying to shoulder its way into them. He checks his course; the bitch has veered a full ninety degrees!

“They’ve seen us,” Bischoff says. “We’ll dive in just a moment.” But before he loses his ability to use the periscope, he does one more three-sixty, just to verify that his mental map of the convoy is accurate. It is, more or less; why, there’s a destroyer, right there where he thought it was. He steadies the ‘scope, calls out target bearings. The Torpedomaat echoes the digits while dialing them into the targeting computer: the very latest fully analog technology. The computer grinds through some calculations and sets the gyroscopes on a couple of torpedoes. Bischoff says:
fire, fire, dive.
It happens, almost that fast. The diesels’ anvil chorus, which has been subtly driving them all insane for a couple of days,
is replaced by a startling silence. They are running on batteries now.

As has always been the case, and as will continue to be the case for at least another half century, batteries suck. The convoy seems to bolt forward as U-691’s speed drops to a pathetic wallow. The destroyers can go about five times as fast as they can now. Bischoff hates this part.

“The destroyer is taking evasive action,” says the sound man.

“Did we have time to get the weather forecast?” he asks.

“Storm front moving in this evening. Foul weather tomorrow.”

“Let’s see if we can stay alive until the storm hits,” Bischoff says. “Then we’ll run this bucket of shit straight up the middle of the English Channel, right up Winston Churchill’s fat ass, and if we die, we’ll die like men.”

A terrible clamor radiates through the water and pierces the hull. The men cheer sullenly; they have just sunk another ship. Whoopdy-doo!

“I think it was the destroyer,” says the sound man, as if he can hardly believe their luck.

“Those homing torpedoes are bastards,” Bischoff says, “when they don’t turn round and home in on
you.
”

One destroyer down, three to go. If they can sink another one, they have a chance of escaping the remaining two. But it’s nearly impossible to escape from three destroyers.

“There’s no time like the present,” he says. “Periscope depth! Let’s see what the fuck is going on, while we’ve got them rattled.”

It is like this: one of the destroyers is sinking and another is heading towards it to render assistance. The other two are converging on where U-691 was about thirty seconds ago, but they are hindered by having to make their way through the middle of the convoy. Almost immediately, they begin to fire their guns. Bischoff looses a spread of torpedoes towards the assisting destroyer. Water is spouting up all around them now as they are straddled by shells from the other two. He does another three-sixty, fixing the image of the convoy in his mind’s eye.

“Dive!” he says.

Then he has a better idea. “Belay that! Surface and go to flank speed.”

Any other U-boat crew would cut his throat at this moment, then surrender. But these guys don’t even hesitate; either they really do love him, or they’ve all decided they’re going to die anyway.

Twenty seconds of raw terror ensue. U-691 is screaming across the surface, banking like a Messerschmidt as shells pound into the water all around her. Crewmen are spilling out of her hatches, looking like prison camp inmates in the bright sun, trying not to slide off the deck as it tilts this way and that, diving to snap the carabiners of their safety lines onto cables before they are blown out of their shoes by the waterspouts from the exploding shells. They are manning the guns.

Then there’s a big transport ship between them and the two destroyers. They’re safe now, for a minute. Bischoff’s up on the conning tower. He turns aft and gets a load of the other destroyer, spiraling crazily in an effort to shake off those homing torpedoes.

When they come out from behind the shelter of the big transport, Bischoff sees that his mental map of the convoy was more or less accurate. He speaks more orders to the rudder and the engines. Before the two attacking destroyers have a chance to open up with their guns again, Bischoff has got himself positioned between them and a troop transport: a decrepit ocean liner covered with a hasty coat of wartime camo. They can’t shoot at him now without blowing hundreds of their own troops to shreds. But he can shoot at them. When Bischoff’s men see the liner above them, and gaze across the water at the impotent destroyers, they actually break out into song: a congratulatory beer hall ditty.

U-691 is topheavy with weaponry, armed to the teeth because of the aircraft threat. Bischoff’s crew opens fire on the destroyers with all of the small and medium-sized stuff, to give the deck gun crew a chance to line up its shot. At this range, the danger is that the shell will pass all the way through the destroyer’s hull, and out the other side, without detonating. You have to be patient, take your time, aim for the engines. Bischoff’s crew knows this.

A skull-cracking explosion sounds from the barrel of the
deck gun; the shell skims the water, hits the closest destroyer right in the boilers. The destroyer doesn’t blow up, but it does go dead in the water. They take a few more shots at the other destroyer and manage to knock out one of its guns and one of its depth charge launchers. Then the lookouts see airplanes headed their way, and it’s time to dive. Bischoff does one final periscope scan before they go under, and is surprised to see that the destroyer that was trying to evade the torpedoes managed to do so; apparently two of them curved back and hit transport ships instead.

They go straight down to a hundred and sixty meters. Destroyers drop depth charges on them for eight hours. Bischoff takes a nap. When he wakes up, depth charges are booming all over the place and everything is fine. It should be dark and stormy up there now: bad weather for Catalinas. He evades the destroyers by (in a nutshell) doing clever things he has learned the hard way. The U-boat is as thin as a knitting needle, and when you turn it directly toward or away from the source of a ping, it makes almost no reflection. All that’s required is a clear mental map of where you are with respect to the destroyers.

After another hour, the destroyers give up and leave. Bischoff takes U-691 up to schnorkel depth and points her straight up the middle of the English Channel, as advertised. He also uses the periscope to verify that the weather is, also as advertised, awful.

Those bastards have a big fat red pin on the map marking his position as last reported by those destroyers. Around that pin, as the hours go by, they will draw circles of steadily increasing radius, widening gyres enclosing the set of all points in the ocean where U-691 could possibly be at the moment, based on their assumptions about her speed. The square mileage that must be searched will increase as the square of that radius.

Going up the Channel,
while submerged,
just isn’t going to work—they’ll run into one of the block ships that the Brits sank there to prevent U-boats from doing just that. The surface is the only way, and it’s a hell of a lot faster too. This raises the airplane issue. Airplanes search not for the boat itself, which is tiny and dark, but for its wake, which
is white and spreads for miles on calm water. There will be no wake behind U-691 tonight—or rather, there will be, but it will be lost in random noise of much higher amplitude. Bischoff decides that covering distance is more important than being subtle at the moment, and so he brings her up to the surface and then pins the throttle. This will burn fuel insanely, but U-691 has a range of eleven thousand miles.

Sometime around noon the next day, U-691, battering its way through a murderous storm, lances the Straits of Dover and breaks through into the North Sea. She must be lighting up every radar screen in Europe, but airplanes can’t do much in this weather.

“The prisoner Shaftoe wishes to speak to you,” says Beck, who has gone back to being his second-in-command, as if nothing had ever been different. War gives men good ignoring skills. Bischoff nods.

Shaftoe enters the control room, accompanied by Root, who will apparently serve as translator, spiritual guide, and/or wry observer. “I know a place where we can go,” Shaftoe says.

Bischoff is floored. He hasn’t thought about where they were actually
going
in days. The concept of having a coherent goal is almost beyond his comprehension.

“It is—” Bischoff gropes “—
touching
that you have taken an interest.”

Shaftoe shrugs. “I heard you were in deep shit with Dönitz.”

“Not as bad as I was,” Bischoff says, immediately perceiving the folksy wisdom of this American barnyard metaphor. “The depth is the same, but now I am head up instead of head down.”
