		2)	U 154 sank a 4,000 tonner in DO 72 on 4.4, a 6,000 tonner in DO 74 on 5.4 (Catokula, 5,030 BRT). Both auxiliary war ships or transports. Strong air patrol in Mona Passage. Intends to operate in Windward Passage.
	b)	None.

	d)	None.

IV.	Current Operations:
	a)	None.
	b)	1)	Square of approach for U 507 and U 125 is DD 85. It is intended to operate these boats from the Florida Straits north of Cuba to Windward Passage. On their way there, boats are to observe density of traffic in DD and DC.
		2)	Boats in the American coast area are to have freedom of action according to fuel and state of defense.
			In order to make full use of the present favorable conditions for attack (new moon) they are ordered to start their return passage without fuel reserves. In emergency they can be supplied from tanker - 459.
	c)	U 582 reported from CD 57: Rio Grande not encountered. Am proceeding westward.
		This is the third time that a U-boat has failed to contact a blockade breaker. This is the more regrettable as the fighting power of the boat for further operations has been weakened considerably, and in most cases completely reduced owing to consumption of fuel and provision.
	d)	None.

VI.	General:
	The following situation in the American area emerges from U-boat W/T messages and reports from C.O.'s who have returned:
	Anti-S/M activity immediately under the coast has increased. Destroyers, Coast Guard ships and escort vessels are patrolling the steamer routes, sometimes ships are escorted by escort vessels in particularly endangered areas (Hatteras). In spite of these measures, the successes of U-boats have so far remained at the same level. Before the U-boat attack on America was begun it was suspected that American anti-S/M activity would be weak and inexperienced; this conjecture has been fully confirmed. Anti-S/M vessels have no Asdic, some are equipped with hydrophones. The crews are careless, inexperienced and little persevering in a hunt. In several cases escort vessels, Coast Guard ships and destroyers, having established the presence of a U-boat, made off instead of attacking her. This can only be the only explanation of the fact that so far no losses have occurred from D/C hunts in shallow water (20 meters).
	Air activity has also increased considerably. Boats are forced by it to remain submerged by day near the coast. On full-moon nights it is dangerous owing to the numbers of aircraft involved and boats are forced to transfer their attacking areas further out to sea.
	On the whole however, the boat's successes are so great, that their operation near the coast is further justified and will continue.
	With regard to disposition on the coast, so far the boats have been given freedom of action in all areas which their fuel stocks will allow them to reach. With the appearance of the first U-tanker (U 459) the range and operational endurance of the boats will be extended when they have been supplied and the number of boats in operational areas will increase. This will inevitably mean new allocation of attacking areas. If the stretches of coast which the Americans have to defend are extended, they will need to increase the number of anti-S/M vessels considerably. These anti-S/M vessels cannot be raised as fast as all that, there will continue to be particularly favorable points for attack and from time to time anti-S/M vessels will of necessity have to be withdrawn from coastal stretches which are specially defended. At least anti-S/M activity will not be increased in the latter areas.

		Form "Canaveral" to "Hatteras" all lights as in peace-time. Heavy traffic in spurts. South-going traffic close under land inside the 20 meter line, following the bays south of Cape Fear. North-bound traffic proceeds 5 sea miles east of a line Hetzel Shoals - St. John's lightship - Savannah lightship and Frying Pan Shoals direct. There is an airfield near the south mole of St. John's River. A lot of air activity here, with and without lights. At night flares along steamer routes, good cooperation with destroyers by means of searchlights. During a D/C hunt by destroyers, the enemy did not stick with it and made off too soon. No Asdic, good listening conditions. Boat is conditionally fit for return passage.
		Further successes:
		Off Jacksonville Beach full tanker"Schehezerade", 12,500 BRT, off Brunswick buoy tanker type "Esso Balboa", 9,554 BRT, tanker type "W.B. Walker", 10,468 BRT, off Hetzel Shoals buoy tanker 8,000 BRT. All tankers full. As we were in shallow water, parts sticking up out of the water were destroyed by gunfire. In addition, "Esparta" 3,365 BRT and a passenger freighter 5,500 BRT. Total: 74,837 BRT sunk.

II.	Air Reconnaissance: None.

III.	Reports on the Enemy:
	a)	Situation report U 203 off Hatteras:

- 18 -

		Heavy traffic, mostly making for the bays, behind the 25 meter line. Usually pass the Capes in daylight. Approach buoys lit up, guarded by anti-S/M vessels. Diamond Buoy is rounded very closely or passed on the inside. Patrol numerically strong but entirely unpracticed. No (radar) location observed. A/c day and night, destroyers, fishing smacks. S/M chaser type PC 451 has an unpleasant, flat silhouette. Valuable targets have air escort. Deterrent D/C's and a/c bombs, on one occasion flares. Listening conditions very variable, but always greater range than through periscope. On account of murky water, a/c can hardly be seen at periscope depth.
		Situation report U 654:
		Net barrage off Hatteras along 100 meter line from 35 degree north to 30 sea miles to the north. An extension to the south seems intended. Black buoys and barrels. D/C's from escort vessel while submerging. Empire Lightening 7,000 BRT sunk.
	b)	None.
	c)	U-boat sightings: S.S. Greylock, 7,460 BRT in DC 27; further in DB 61 - CA 81 - DB 91 - CA 73 - DC 12 - CA 81 - DB 36 - ED 62.
		SSS report: S.S. "Jean" 4,902 BRT in DB 91 further from DC 12 - BA 97.
	d)	None.

IV.	Current Operations:
	a) -	c)	None.
	d)	U 252 has been ordered to make a situation report, has not replied. It is feared that the boat may have been lost at the convoy in BE 55. Circumstances here were similar to these in the loss of U 82: the same sea area, a south-bound convoy with apparently weak escort (5-10 vessels, 2 escort vessels identified), favorable weather conditions (new moon). Boat was on return passage, this time with ample supplies of fuel and torpedoes. She had permission to attack only if conditions favorable, (to move off before first light), and yet another boat is lost. I think it is possible that, in this area, trough which a stream of west-bound U-boats passes, the English sail a dummy convoy of special anti-S/M vessels. I have therefore forbidden attacks on convoys in this area for the present.

V.	Reports of Success:
	U 654 - 1 ship - 7,000 BRT.

VI.	General:
	On 15.4 3 months have elapsed since U-boats made their first appearance on the east coast of America and since the weight of all U-boat activity was transferred to that area.
	During this time 229 ships of 1,521,000 BRT have been reported sunk and 23 ships of 82,506 BRT damaged in the NOrth Atlantic alone, i.e. excluding sinkings in northern waters, in the Mediterranean and on

c)	that U-boat warfare must continue to be concentrated on the east coast of America as long as conditions of anti-S/M activity and possibilities of successes remain at all the same as they are at present.
