	First patrol of the Kommandanten with a new boat.
	1.)            The decision of the Kommandanten on 26 January to operate on the convoy reported by"U-752" showed attack spirit, but was not thoughtful enough.  To operate on an outbound convoy when only one boat is on it and the initial distance is already 400 nm, so that the Kommandant must chase for a minimum of 4 days, promises very little chance of success, especially since the operation must take place in air-surveiled area.
	2.)            When calculating the fuel consumption for the return transit one must not expect the prevailing bad weather conditions for the entire return.  In bad weather dive and proceed submerged.
	3.)             In the verbal report of the Kommandanten it came out that on 13 February, after receiving the order to head for a new area, it was not clear if he should break off the operation then existing on the convoy at that time.  Own enemy contact always comes first.  If the B.d.U. wants the current operation to be broken off, this will be ordered expressly.
	4.)              On 24 February the course change and one-hour running off made on the basis of presumed locating gear, without any self-observation, was too cautious.
