variation in salt content which affected buoyancy.
'So much for stealth,' Ilse said. 'That shore battery woke up the whole neighborhood.' The message light blinked.
'Source this time is bearing two nine five,' Meltzer said. From the direction of Denmark, not Sweden.
'Put the 'scope on two nine five,' Jeffrey said.
Meltzer reached and turned a knob. 'That's a German patrol craft, Captain, approaching fast.' They were cornered.
The patrol craft was barely two thousand yards off, coming straight at them on the screen. Jeffrey saw a big radar dome on a pylon over her bridge, and a big gun on her foredeck. He glanced at Ilse; she looked stoic, resigned. He saw her finger the pistol on her belt.
Montgomery said the acoustic message was in code. He couldn't decrypt it.
'Mechanical transient bearing two nine five!' Meltzer said. Jeffrey saw it on the broadband waterfall. 'Replay on speakers.' The control compartment filled with a clanking, a harsh electrical whine, then a thunk. There was awful finality to that thunk.
'That's a deck gun loading and — training,' Jeffrey said. On the screen the patrol craft's gun barrel seemed aimed right between his eyes.
'That thunk was the breach block closing, wasn't it?' Ilse said. 'What do we do?' Jeffrey could see she was panicking. He forced himself to stay levelheaded, which wasn't easy. He had an idea. 'Chief, answer them on digital using plain text. Say it's our first day.' The western Baltic was a German Navy training area.
Montgomery grinned, and typed.
The warship answered. 'They want the recognition password.' Uh-oh. 'Tell them, tell them you can't remember. In training they said to never write it down. That gun aimed down your throat is making you nervous…. Write with a lot of typos so they think you're flustered.'
Montgomery took a deep breath. He typed.
There was a long, nerve-racking pause. Jeffrey waited for the gun to open fire. He'd see the flash, then hear it, then feel it, then feel nothing.
Montgomery frowned. 'They say to stop where we are.”
Ilse pulled the pistol from her belt. Jeffrey put out his hand to stay her. Jeffrey almost jumped when he saw flashes on the screen — but they were much too fast for a three-inch gun. A signal lamp, aimed at the minisub's periscope.
'Morse code, plain text,' Montgomery said.. 'They're sending a minesweeper to escort us to the Baltic.'
Jeffrey took the pistol from Ilse and safed it and put it back in her holster. 'For the last time,' he told her. 'This is about the mission, not about you.' More lights flashed from the patrol craft, and another ship hove into view. That ship signaled.
'She's the Konstanz,' Montgomery said. 'One of those Type three-fifty-one minesweeping-drone control ships. She says to fall in behind her, she'll send her drones out in front.'
'Does this periscope have-a signal light built in?' 'Yes.'
'Then tell them thanks.'
Montgomery keyed the message.
'They say they were going to make a routine sweep soon anyway. You never know when an Allied unmanned aerial vehicle might sneak through and drop a mine…. They also say, based on our performance the last few minutes, we might want to reconsider our career choice.. like maybe the Army.' Ilse held on as the minisub pulled into the minesweeper's wake. The mini began to roll heavily. Ilse was glad she had taken a seasick pill before leaving Challenger.
'Try to keep the periscope aimed at their stern,' Jeffrey said.
'Aye, aye,' Montgomery said.
Ilse studied the picture. She could see boat davits on the Konstanz's afterdeck. Then came the superstructure, with a single mast. A yellow light blinked on the masthead.
'What's that for?' Jeffrey said.
Montgomery riffled through the mini's on-line database. 'I am escorting a friendly submarine.'
Two crewmen came to stand at the minesweeper's stern.
'An officer and a phone-talker, I think,' Ilse said. They wore battle helmets and life vests over foul-weather gear. She saw the officer look at her through big binoculars. A third man came over with a handheld signal lamp. He flashed a message.
'They say it would be safer if we surfaced,' Montgomery said.
'No,' Jeffrey said. 'Tell them we're low on fuel. We get better mileage submerged.'
'They want to know how much fuel we have.' 'How much do we have?'
'Eighty-two percent.'
'Tell them forty.'
'They want to speed up to ten knots. They have a lot of ground to cover. Can we make it to Bornholm Island at ten knots?'
'Why Bornholm?' Jeffrey said.
'That must be their training base for minis.'
'Can we?'
'Yes, sir,' Meltzer said, 'running submerged. I memorized the speed/endurance curves.'
'Can we make it to Greifswald and back to Challenger after that?'
'Greifswald, yes, sir, if we go slower. Back to the ship, no way, even at optimum cruising speed.'
Jeffrey worked his jaw again. 'Chief, tell them Bornholm is okay but we prefer to go slower.'
'They say we can refuel when we get to barracks. They have work to do, and they're doing us a favor.'
'Blade-rate increase,' Meltzer said. 'They're speeding up.' The signalman blinked. Montgomery translated.
'They said if we run out of gas they'll give us a tow…. The German inflection is hard to convey in English, Skipper, but it's sarcastic:'
'Ten knots it is.'
A few minutes later, on the periscope screen Ilse saw a sharp yellowish glare. There was a terrific detonation, ahead and to port of the Konstanz. She saw a mountain of water bursting skyward. It dropped back slowly, drenching one of the Troika drones. The officer on the minesweeper's stern spoke to the signalman. They waved to the mini's periscope. Ilse thought they were laughing. Cocky bastards.
'Sir,' Meltzer said. 'I hate to bring it up again, but the mission. Getting back. How do we refuel?' Jeffrey frowned. 'We'll deal with that when we have to…. How long to get to the Baltic?'
'At this speed, Captain, six hours.'
'Those of us who can ought to get some sleep.'
'Concur, sir,' Montgomery said. 'The pilot and copilot reliefs will come forward soon enough.' Some of the enlisted SEALs were trained in this duty. Montgomery reached for a thermos of coffee under his seat, and offered it to Meltzer.
'Ilse?' Jeffrey said. 'Let's go aft. They saved the two front seats for us.' Before he left the control compartment, he glanced at the fuel gauge and the chronometer. We're falling more and more behind schedule with each new development, and lower and lower on fuel. This is starting to look like a suicide mission.
Jeffrey jerked awake with a start: Something had scraped the top of the hull. He looked up frantically. A tethered mine?
'Just brash ice, sir,' Chief Montgomery said from the aisle next to Jeffrey's seat. 'Time to get up anyway, Captain.'
Jeffrey looked at his borrowed dive watch: 1723 Berlin time-5:23 P.M., after dusk already this far north, so close to the shortest day of the year, the official start of winter. Jeffrey had slept more than nine hours straight, for the first time in weeks. That explained why he felt so good.
The lighting was rigged for red. Montgomery handed him a steaming cup of coffee, then went forward. Jeffrey drank. He glanced across the narrow aisle. Ilse was wide awake.
'Where are we?' Jeffrey said. He ran his fingers through his hair.
'Entering Greifswald Bay,' Shajo Clayton said from behind him. 'Now comes the fun part.'
