Phil - we start from Gib, that is why I suggest we feint south to throw them off our tracks. The U boats will not be close to Gib - too many planes etc - but agents will watch from just over the border and report a large convoy leaving.

One tactic we have not mentioned is the fake attack - at night several escorts go off from the convoy - say 5 miles and mock up an attack - loads of snowflake, depth charges etc. The U boats see that and move towards it thinking it must be another boat attacking the convoy, pulling them away from the real convoy. probably only to be used when we think subs are near. Shall we add this to our arsenal?
