It's early '43 and I'm stalking a convoy. Whats the best way to attack a convoy thats basically surrounded by destroyers? I can sometimes manage to sink one, at the expense of a four torp spread, so I surface, thinking I'm safe, then two more destroyers come out of nowhere. They don't let me get anywhere near the merchants. I can't even get close enough to launch my torps and hope they hit something; the ships are simply out of range. I hate these destoyers! Any suggstions?

There is usually a gap in the front corners of the convoy between the lead destroyer and the first flank destroyer. You must stay wide enough to avoid getting detected by the lead DD but close enough to get behind him before the flank DD detects you.
I also suggest you start using some renown to buy ladder torpedoes and homing torpedoes to hit the escorts if detected.
1943 is when the tide changed dramatically so things should be more difficult for all U-Boats.
If you can not get in correctly do not force your way in or you will be attacked.
Go behind the convoy and as the last escorts pass you fire a homing torpedo into the merchant ships. You will sink a smaller one or disable a big one because the homi targets the propellers and you can finish the ship off when the convoy moves on.

By 1943, there are no more surface attacks.

Getting in a good positions ahead of the convoy is more important than ever.

The starboard side of the convoy is the best to try for if you are following Wolfmans idea.

(It is also my tactic.)

The reason for this is because the lead escort follows the first colum of ships. If there are 3 colums it is easy to see he will be ahead of the middle of the convoy. (Or at least Zig Zagging around that point.)

If you have 4 colums though he has to be off to one side because he is still ahead of the lead colum. The extra colum is set up on the starboard.

This MIGHT push the starboard escort out a bit more and give you more room. But more importantly it gives you a measure stick against how far you are from the lead escort. Even from the hydrophones you can usually get an idea if you are on the corner of the convoy. And the starboard corner is always tied or farthest from the lead escort.

Now that the escorts have radar, you have to get in front of the convoy some 20Nmiles and submerge. From here you have to position yourself, via hydrophones and minimum scope usage, on the port (left) or starboard(right) corners.
Keeping far away from the front escort so he doesn't ping you. And of course 'Silent Mode' and speed <= 1knot.

Hopefully the convoy doesn't change course http://forums.ubi.com/images/smilies/bigtears.gif

I usualy go slow ahead.
But usualy the know I'am there is when the first Tanker or other high profile targets go up in flames http://forums.ubi.com/images/smilies/59.gif but then it is to late. http://forums.ubi.com/images/smilies/784.gif

i have only met two convojs and one of them were neutral so i dont have much experience
but i was thinking about a taktik that i intended to use for the "next" convoj

if u spot a convoj u could go in fornt of it so it would sail over u then hit 30-60 meters deapth and wait for them to sail over u
when theyre direktly over u then suface at night or periscope at day and the party can begin... how to get out i dont know

You might want to look over the Murmansk series of reports I posted. Those were all convoy attacks, though quite a few were done in conjuction with Luftwaffe attacks. The early attacks were made with a loadout of all electrics, which made things pretty tough. In 1943 you'll get Falcons and Wrens along with FaTs.

Ideally, you'll want to position ahead of the convoy and off to the side 2,000 meters or so. In the Murmansk accounts, I would typically (though not always) make contact, send a report to BdU, and then reposition. The contact report will give you exact course and speed of the convoy which will simplify targeting. Note: the Murmansk convoys (to Murmansk) are always traveling at 12 knots.

Once you have exact course/speed you can set up for a keel shot on the high value targets in the center of the convoy. Use FaTs and the magnetic pistol on those. Note: best is to attack at night.

Here's the way a night attack with good visibility and moderate to light (&lt;= 7 m/s) winds might play out:
<UL TYPE=SQUARE>
<LI>Hydrophone check picks up convoy.
<LI>Figure course, get in position.
<LI>Make contact. Take sightings and establish convoy configuration.
<LI>If the position is good - 1,000 to 2,000 meters off of a flank column - proceed with the attack. Note: flank escorts will frequently conduct searches several thousand meters off to the side of the convoy. This can create a hole you can use to get closer to or even inside the convoy. Take advantage of it if this situation arises.
<LI>If using FaTs, position perpendicular to the convoy's course. Set depth 0.5 to 1.0 meters below keel. Tankers ride fairly deep and your shot will probably have to pass under outer columns. When I have FaTs I like to put them in tubes I & IV with conventional torps in II & III. The idea is to fire single FaTs at the tankers and a spread of 2 conventional torps at a large container ship on the outer column. The spread shot can be impact.
<LI>When you are ready to fire, target the trailing tanker first, then switch to the leader. Take the outer shot last, then dive and turn away probably (though not always) toward rear of the convoy. If escorts close, release decoy at 50 meters or so.
<LI>If you get hits, wait for main convoy to leave and check for cripples.
[/list]

Note: clear weather and calm seas makes shooting easy but also makes it much easier for the escorts to spot you. Moonlight is problematic - lookouts can see your periscope. When silent running, make only 1 knot.

Final note: abort an attack if you can't get a good shot or if escorts appear to be too close. You can usually reacquire a convoy. On some of the Murmansk patrols I attacked the same convoy multiple times.

I usually use Paulhager's approach too. I'm in Jan 45 now and attacking convoys is harder than ever. I often use the FAT fish launched from the side of the convoy at 1000 to 2000 meters. I've even done it without using a periscope sighting from completely underwater using hyrophones to estimate the position. I got 2 good kills that way. The accoustic homing fish work to but you need to space them out more as if you salvo fire them they will home in on each other.
My favorite escape tactic is after shooting off my load is to head toward the convoy at flank - let them hear me - while diving. At 100m release decoys near the edge of the convoy, then continue under the convoy to 175 to 200m while running silent at 1-2 kts. Come out the other side and sneak away.

I'm on my way home to Bergen (Norway) in Jan 45 now to finally get my XXI boat. I just sunk 77K tons in 3 days in sectors BF17 and BF14. I had 30,700 reknown points already so I should be able to buy the uber sub if I can make it there. I'm being tormented by planes something terrible trying to get home around the top of England. I counted 20 of them above me at last dawn and was forced to dive. I've got enough fuel to run at flank all the way home but I keep getting attacked every 20 minutes. Too windy now to use AA guns although I already have 22 plane kills. Wish me luck!

Like real-life, the further into the war you get, the harder it is. From 1943 on I go to a different mind-set. At the start of the war I would fire one fish at 4 targets and then wait and pick off the cripples. Later in the war I am much more inclined to fire two or three fish at one target for a sure kill and then get the hell out of dodge. Late war I find that the escort groups are more inclined to stick around the cripples and make it a less attractive tactic. Better to get one or two kills per patrol and live to fight another day.

There is also something to be said about the level you are playing and if you use reset after death.

I play at 100% and if I am killed I start over. No excuses even bad luck in TC I have no tolerance for my stupidity..

22 aircraft shot down? I will go out on a limb and guess you are not playing at 100%. http://forums.ubi.com/images/smilies/10.gif

I also have doubled the number of escorts and have no escort with less than a 3 crew rating in the game.
Is anyone surprised I have never once finished the war in playing every day for a year!!???? http://forums.ubi.com/images/smilies/88.gif

I recently attacked a convoy Jan 44 that had the escorts coming after me before I could get off a shot.
I had bought extra homing fish and had sunk 5 escorts but the other three hunted me like a dog and I started a new career the next night! http://forums.ubi.com/images/smilies/compsmash.gif

Yea, ok..I play at 60% realism. I don't want the game so hard my hair falls out. Also, this is my first career still but If I play another I will likely make it harder since I now understand what it takes to survive better.
Yes..22 planes! Actaully I finished up the mission with 25 plane kills. Why so many? 1. I have experienced flak gunners. 2. Long stretch of good weather. 3. I have good plane fighting tactics. 4. I have the dual auto-loading 3.7cm gun which in my opinion is the best AA gun in the game. Also, I opted for the type 4 radar detector which is a big help.
But alas..I won't be getting that many planes kills anymore. I just traded in my IX-C boat for a XXI. Plus, it's March 17th 1945 now and this is problably my last mission of the war. Then its off to Nurnburg to be tried on war crimes for all the helpless souls I've sent to the bottom of the Atlantic. I hope they get the noose right.

You see this is why I think I play at the 'Correct Realism'.
I rarely see a/c ( this is largely dependent of the routes I take = common sense[hindsight]).
I usually make only one attack per convoy, sinking 1 to 2 ships, then get attacked by escorts for a few hours. The escorts have varied experiences, which seem logical. Sometimes they make a few attacks and leave, but then there are the determined lot which hang on for hours??

Max speed is 512x to invite radar A/C for tea.

I'm generally very cautious, but go nuts when opportunity strikes.

I'm on my one and only career Spt39-March43 and still going strong at 100%, RuB, Radar.... not to mention my siggy http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif
