		2)	Group "Dragoner".
			3 boats belonging to Group "Landwirt" are to be deployed at the western approaches to the Channel in order to gain experience in these waters in case of invasion and in warfare against enemy destroyer groups in their own coastal routes. The boats are to form the Group "Dragoner", and will occupy the area between the longitudes from the center of BF 2828 and the left edge of 2924. 2 boats west, one boat east of the barrier Richard Bruno. Southern boundary parallel to route "Herz" at a distance of 5 sea miles, at night central point to the south; this to be extended to route "Herz" on nights when there

- 291 -

		is none of our convoy traffic.
		Boats are to remain principally submerged, to charge batteries with "Schnorchel" apparatus and to receive continuous enemy reports from Senior Officer U-boats West on the U-boat coastal long and short waves.
		Return passage after first success or first observation by the enemy - apart from invasion. Period of operations to depend on the situation here against U-boats.
		No great danger for the boats anticipated at first, as enemy defences are not in operation here against U-boats.
		U 764 put out as the first boat of the Group "Dragoner".

V.	Reports of Success:
	U 736 1 ship 1 hit possible.

35 aircraft of 19 Group were confirmed in the Biscay area.

According to Japanese reports, enemy aircraft over U-boat at 0632 German Official time, in presumably grid MP or MQ. No Japanese boat in the vicinity.

Aircraft belonging to 15 Group reported submerging U-boat at 1658 on 22.5., course 220⁰, speed 18 knots. Position unspecified. Aircraft was D/F'd by Husum in 282⁰ and probably belongs to convoy squadron "Orchestra" - according to wireless traffic, the area west of Ireland, in any case east of 15⁰ W.

Gibraltar patrol sighted U-boat in CG 9672 at 0711 on 23.5. Another U-boat sighting by a Gibraltar aircraft at 0925 in 36⁰ N., western longitude unspecified - only periscope sighted. As a result of these reports, two more aircraft were sent out from Gibraltar. Also U-boat sighting at 1200, 03⁰ 50' E., latitude unspecified.

IV.

Current Operations:

U 269 put out from Brest on Group "Dragoner" operation.

b) -

None.

U 66 must be presumed lost. The boat sailed from Lorient on 16.1. and carried out successful operations off the coast of Guinea. Provisioning for the return passage was to be executed from U 488. As U 488 was presumably lost at the assembly point on 25.4., a new meeting between U 66 and U 515 was ordered, and as this boat did not appear between U 66 and U 188. This meeting must have taken place as U 66 subsequently reported an increase in fuel and provisions. Only a small amount of supplies were taken on from U 188 as this boat had little to give. Last message from U 66 was on 6.5. and ran "Aircraft attack; aircraft maintaining contact. Attack by surface forces in EH 2546".

- 298 -

			Fuel supply was last reported as 23 Cbm., provisions sufficient to last at the outside until 15.5. so that a further supplying would have to take place from U 198. Meeting was ordered - neither boat put in an appearance.
		2)	U 198 put out of La Pallice on 24.4. and sent a passage report on 3.5. from DH 2581. The boat received position for the supplying of U 66 on 11.5. - Grid DS 2746, no more news has been received, however, so that the loss of this boat must also be presumed. Cause of the loss of both U 66 and U 198 was apparently combined carrier-borne aircraft, U-boat chaser group operations.

Addition:
U 198 reported her position from FN 2784 on 30.5. Owing to wireless telegraphy breakdown the boat did not pick up the messages dealing with the supplying of U 66 (see KTB of 29.5. paragraph IV d).

		3)	As a result of these new losses refueling and reprovisioning are only to take place in an emergency, and are only even then to be carried out by operational boats. This also applies to the mid-Atlantic.

V.	Reports of Success: None.

		4)	Enemy units were located in: AL 4737 - 8433 - DJ 1118 - CF 2232.

IV.	Current Operations:
	a)	Group "Dragoner" received two orders to surface as enemy surface forces had been located: 1) at 0025 - 0055 and 2) at 0405 until dawn. The numerous sightings and ASV locations of the last two days indicate that the enemy is aware of the presence of U-boats and has intensified

	a)	1)	U 129 begins return passage from the east coast of Brazil. The boat sank a freighter of 4,000 GRT in FK 67 and a steamer "Empire Heath" in FR 45. Situation report: Neutrals south of Rio de Janeiro, numerous fast isolated vessels and neutrals from FQ 7880 - 5540. Boat did not come across any defence and remained unobserved.
		2)	U 1222 fired a double spread miss (explained) on an isolated tanker of 7,000 GRT in BB 7850, course 0⁰, speed 11 knots.

- 304 -

			Further, a small convoy sighted, according to hydrophone bearing in BB 7570 on south-westerly course, on 21.5. In 24.5. isolated vessel in CB 2552, southerly course high speed, and in CB 2521 a tanker with two escort craft, course 80⁰, speed 8 knots. Defence: At night air activity with lights, "Naxos" location after being observed. Inexperienced escort vessels in BB 75/78.
		3)	In addition, U 541 reports with reference to the "Serpapinto" affair (see KTB of 26.5. III a) 1)). Contraband on board, crew and passengers allowed to leave ship, awaited orders. Ship then allowed to proceed. 2 Americans retained on board. Greek steamer "Thetis" was examined. Goods for Switzerland allowed to proceed.
	b)	None.
	c)	1)	24 aircraft of 19 Group were confirmed in the Biscay area.
		2)	U-boat sightings:
			Aircraft of 18 Group reported: 1) U-boat on surface in AF 7381 at 0817; 2) U-boat on surface in AF 7621, course 300⁰, speed 6 knots at 0822.

IV.	Current Operations:
	a)	As U 955 is homeward-bound, U 853 occupied this area. U 857 takes up U 853's position. Weather reports as ordered.
	b)	None.
	c)	As time for meeting between U 843 and U 183, 1400 (German Official time) has been decided upon. This is 3/4 of an hour before darkness (see KTB of 24.5. IV c).
	d)	The fact - confirmed by Radio Intelligence reports - that enemy reconnaissance activities have been intensified in the areas AF 70 - 80 shows that the enemy is aware of the increased switch-over of boats to the Atlantic and Northern Waters. The toughness of the fight against enemy aircraft is obvious from the short messages from the two lost boats U 990 and U 476 (see Appendix).

2.6.44.			Appendix 3 to KTB of 27.5.44

Report on "Dragoner" operation.

1)	Not a success. Only likely to prove effective under the following favorable circumstances:
	a)	The presence of valuable German units in the operational area.
	b)	Knowledge of this maneuver by the enemy and deployment of larger enemy units (from destroyers upwards).
	c)	Timely interception of the enemy by location centers.
	d)	Favorable attacking positions for the U-boats which can only be very slightly improved on in the short time available for operations.
	e)	Complete surprise to the enemy, who must not have located any boat before the action.

2)	The conditions according to 1) a) and b) were lacking, as MTBs. were out of the question as decoys after running into mines. The movement of less valuable targets on a short route near the U-boat's operational area as bait was inadequate. Condition according to 1) e) no longer in force at the latest from the night of 23.5.

3)	Operation of Schnorchel boats only possible on moonless nights.

4)	Radio beacons were only occasionally D/F'd by U-boats in spite of long transmissions favorable to U-boats - positions were therefore often inaccurate and unfavorable for attack (too far from route "Herz").

5)	Operations provided valuable experience:
	a)	For the Command: Co-operation with location centers; the clearing of radio traffic with "Schnorchel" boats in this operations area (more isolated short messages for surfacing and submerging necessary). Armament maintenance impossible, "Schnorchel" time limit, "Schnorchel" locations.
	b)	For the boats: Knowledge of operational area navigation, schnorchel ling, radio traffic (Y signals).

	1340	in	AF 8146	"periscope sighted".
	1653	in	AF 4977	"over boat".

	1756	in	AF 8449	"over submerging U-boat, course 0⁰"
	2215	in	63.35 N., submerging U-boat, course 45⁰, longitude
				unspecified.
	2250	in	AF 8162	periscope sighted, course 90⁰, speed 5 knots.

Especially lively day for 18 Group (25 aircraft confirmed).

No ASV locations.

English units were located in: AL 5550, BE 3399, 8440, 5757, 9522, AM 4350, 9240, 4187, 6521, 7865, 8180, 4260, 5530 (American).

	d)	None.

IV.	Current Operations:
	a) -	c)	None.
	d)	1)	U 960 must be considered lost. The boat left La Pallice on 27.4. for the Mediterranean. Passage report sent on 2.5. in Grid BF 84, nothing since then. Presumably loss in Straits of Gibraltar owing to intensified patrols.
			As it appears impossible to break through into the Mediterranean, no boats are to proceed there until further orders.
		2)	U 852 must also be presumed lost. The boat left Kiel on her first operational voyage on 18.1.44, bound for the Indian Ocean.
			The boat sank two steamers of 11,685 GRT on the outward voyage and then proceeded through the Mozambique Channel into the Gulf of Aden. The last message received was a report of an aircraft attack on 2.5. in Grid MP 97. Nothing since then. Loss probably as a result of this attack. An English press report of the sinking of a German U-boat by a British aircraft in the Gulf of Aden is available.

V.	Reports of Success: None.
