It is likely I know much more about the U-boats than the escorts.

I felt like a sitting duck during the whole game. However, I think KK is right. The subs had to stay on the surface during the day to keep up with the convoy. While they could locate them at long distance staying in contact and getting a shot was not quite so easy. Following on the surface or running a head and occasionally submerging to get bearings were the tactics.

Daylight attacks meant getting in the path of the oncoming convoy and waiting. Night attacks could be made on the surface, running in for some quick shots and back to safety.

Aircraft made shadowing the convoy much more difficult and kept the boats farther away from their targets. Planes at night and star shells would have been a real damper on their preferred hunting methods.

If there were aircraft they could usually be seen a periscope depth even in the North Atlantic. Other seas they could usually be seen at much greater depths. Walkers tag team approach with his escorts meant that they were more able to maintain a contact, as the ship attacking lost the ping as they passed over the sub.

One way or another we should have been able to detect something when they were in the area but this never seemed to happen. No radar or sonar contacts to speak of.

Also in rough seas sound contacts were lost because of the wave action and contacts needed to be maintained visually. The smoke of the convoy could be seen at about 25 miles in clear weather but in storms it was no easy task.

I am sure that Kurt was as disappointed as I was when it ended just as we were receiving some reinforcements.
