If our subs engage the convoys at night and in packs, there is little need to give out any orders of caution. The commanders are well-trained and capable of judging matters for themselves. Our pre-occupation is on organisation, communication and tactics, tactics more in the sense of gathering the forces necessary for a successful attack on a convoy. Our individual u-boats are more than capable of handling matters of how to engage by themselves. The more we try to restrict and order their actions, the less successful they will generally be.
