Yeah, that was a pain in the ass part. I think I reloaded like 20 times after finally managing to get through.
First thing you should do is kill the soldiers inside the submarine one by one with the silenced pistol. After you've killed them off, plant the bombs. One Nazi is spawned near the ladder of the sub after you plant each bomb, so you'll have two extra Nazis to kill after you've planted both bombs. After you have finished planting both bombs, exit quickly.
Now, right when you come up from the pen, snipe the son of a bitch Nazi who is going to be shooting at you with his MP38 either with your Springfield or Silenced Pistol (he's to the left of the submarine, not standing on it) and you'll take care of the main threat. He is the one that will get you killed 90% of the time when you come up. Afterwards, take out the nearby sailors who will be shooting at you, and then snipe the Nazis who are shooting at you from a distance. Get off the submarine and away from the area as soon as you've taken out the threats, and advance to the left of the port, where you'll be welcomed with tons of gunfire. Keep advancing on and on.
The map will pause and load the next portion of the level, where you have to get through 3 ports filled with Nazis spawning constantly. On the second port where there is a submarine, make sure you take out the Nazi who is sniping at you. I can't remember how many times that bastard took me down.
QUICK SAVE FREQUENTLY in this area everytime you manage to kill a couple Nazis without losing any health.
I advise using a combination of grenades and the silenced pistol (it kills most in 1 shot), but other times you will want to take out the MP38 and unload on the Nazis. Frequently you'll have to stand behind the wall and you'll catch Nazis running out unaware of your presence, for some free kills. Eventually though you'll have to proceed forward.
When you reach the last port, dispatch of the remaining Nazis with grenades and the MP38, and make sure you have the sniper rifle out cause you'll have to snipe a couple of these bastards who will come running at you from across the map with Mausers.
I'm pretty sure that's the end of the map..
