		3)	U 183 is requested to suggest a meeting point with U 177 for the purpose of handing over cipher material for October.
	d)	1)	Directions for "Flieder" to U 161: Remain unobserved from CF 20 until picked up by destroyers, principally submerged by day. Make for Spanish coast by about CG 2260, then proceed along the 100 meter line as far as BF 87. Assembly point with 3 or 4 destroyers at 0745 in BF 8468. "Flieder" is to make for assembly point from BF 8459 on a course of 90⁰ and will proceed 10 sea miles further on a course of 90⁰ if there is no encounter. The destroyers make for the assembly point from grid 8549 on a course of 270⁰ in wide formation. 8 Ju 88's are to lead the destroyers to "Flieder" and to fire 20 red star shells as recognition signal on sighting and approaching "Flieder" as arranged. "Flieder" will report 3 days previously, the date of her arrival at the assembly point. The destroyers will then take up position at 0745 on the date given by "Flieder". Proceed with destroyers via point "Liebe" to Brest. Ground mine escort will be ordered by the destroyers. See also Mining Officer Directive 17 and 22.

VI.

General:

The new situation in U-boat warfare arising from the confirmation of Metox radiation, is brought to the notice of all U-boat Commanders in the following summary.

U-boat warfare has experienced grave set backs in the last few months. U-boats were inexplicably lost in passage and in their waiting position. U-boat dispositions were by-passed by enemy convoys. There were fewer successes.

The reason for this was presumed to be a new undetectable method of location by the enemy. It has now been established by means of research and confirmed by P.O.W. statements that the former Fu. M.B. (Metox) enabled the enemy to locate U-boats by reason of its strong radiation.

This apparatus is to be superceded by the non-radiating "Hagenuk" which will also be used for locating short location transmission on all primary wave area frequencies.

The question of location is thereby decisively altered. At the same time the boats are to be equipped with new torpedoes and strengthened anti-aircraft armament. On this new basis the fight is to be resumed with renewed intensity and determination.

This is to be communicated immediately to all Commanders and through them to the crews. Information on new torpedoes or "Metox" radiation which is highly confidential is not to be given to the crews.

II.

U-boat situation:

On the termination of U-boat operations in the Mediterranean, the situation in the various operations areas, were according to the U-boats as follows:

Coast of North America, Florida Straits, Gulf of Mexico:

Deployed:	U 66	Lost:	None in operations area.
	190
	527
	84
	566
	230

- 141 -

Successes:	U 84	1 ship	6,000 GRT
	66	2 ships	15,000 GRT
	566	1 destroyer

In addition: U 566 and 230 each laid a mine barrier off Chesapeake Bay.

In the entire North American coastal area from CA 50 via the Straits of Florida to the Gulf of Mexico daylight air activity, after being observed night air activity with radar. Convoys sailing along the coast have continuous aircraft and airship protection. For the most part only a few fast isolated vessels outside the 100 meter line. Chances of attack on the whole slight, owing to strong air defence.

Caribbean:

Deployed:	U 84	Lost:	-
	732		-
	415		-
	615		615
	634		-
	572		572
	759		759
	359		359

Successes:	U 732	1 freighter	7,000 GRT
		2 ships	torpedoed
	615		6,000 GRT
	759		13,000 GRT.

Situation: The entire Caribbean area, especially in the isolated passages (Windward, Mona Anegada) strong to very strong air patrol, changing to continuous air activity on U-boat being observed. Convoy traffic as formerly via Trinidad - Curacao - Windward Passage. Isolated traffic protected by air and surface escort. Several small convoys in Trinidad area. Tanker groups sighted west and northwest of Curacao. Day and night location everywhere, especially strong radar in Trinidad area. Slight chances of success owing to continuous air patrol and bad visibility, also strength of crew taxed to utmost by heat and moist atmosphere. On the other hand enemy conditions for defence are favorable. This apparent from the losses. 4 boats = 50%.

North Brazilian coast:

Deployed:	U 653	Lost:	-
	510		-
	406		-
	590		590
	662		662
	185		-

Successes:	U 590	1 ship	4,000 GRT
	510	4 ships	22,000 GRT
	185	6 ships	40,000 GRT.

Situation: There is considerable air patrol with large land and sea based aircraft from Trinidad to Natal. After observation strong air activity with and without Radar. Traffic only in convoys with the exception of small numbers of fast isolated vessels.

- 142 -

Opportunity for attack is therefore proportionally slight. Opportunities for attacking a convoy however, are very good as the convoy protection is inexperienced and easily overcome. On both occasions in which boats encountered convoys very good results were achieved i.e. U 510 in EP 40 on 8.7. sank 3 ships of altogether 21.000 GRT, U 185 in FC 70 on 7.7., 5 ships of altogether 35,000 GRT. The intensifying of enemy air activity in the last few weeks has forced the boats to withdraw from the coast and leave the coastal convoy route area. No further successes were achieved after this.

Coast of Brazil from Natal to Rio:

Deployed:	U 513	Lost:	513
	199		199
	172		-
	598		598
	591		591
	604		604

Successes:	U 513	4 ships	16,000 GRT
	199	2 ships	17,000 GRT
	172	4 ships	26,000 GRT.

Situation: As it is apparent from the losses the Brazilian coast has shown itself to be a difficult and dangerous operations area. With one exception, an attack by surface forces (depth charge attack on U 604), the defence took the form of fast daylight bombing attacks off the coast or heavy land and sea based aircraft to 400 sea miles off the coast. Apart from U 604 which had to be abandoned and sunk as a result of damage sustained in air and depth charge attacks, the boats remaining were most certainly lost in aircraft attacks.

As regards the density of enemy traffic chances of action were considered good. Off Rio de Janeiro and Bahia medium traffic, in general, however, on the appearance of boats sails close to the coast. The appearance of the boats necessitated the transference of the traffic routes of fast isolated freighters far to the south in the Atlantic. U 172 showed special sense of detection here - the boat sank not less than 4 ships on the line FD 50, FK 60, FR 10, GC 10 (4 to 500 sea miles offshore).

Dakar - Freetown - coast of Guinea:

Deployed:	U 306	Lost:	-
	333		-
	571		-
	600		-
	618		-
	757		-
	468		468?
	257		-
	358		-
	382		-
	508		-

Successes:	U 618	1 freighter	17,000 GRT	)	Freetown
	757	1 freighter	5,000 GRT	)	Freetown
	508	3 ships	25,000 GRT	)	Coast of Guinea
	306	4 ships	27,000 GRT	)	Dakar

- 143 -

Situation: Traffic consisted of medium sized convoys sailing near the coast between Freetown and Dakar in both directions. It was not possible to intercept the starting point of the Freetown Capetown convoys on the coast of Liberia or the routes of the convoys from Capetown already in open sea south of the coast of Nigeria. A deployment in patrol channels in EU 90 to intercept the Freetown - Lagos traffic also miscarried. It is possible that there has been a decrease of traffic in this area since 30.5., which could be an effect of the freeing of the Mediterranean for the England - India traffic. The defence situation was in accordance with the small amount of traffic - of slight effect. Medium air activity with and without radar in the coastal area and up to 200 sea miles off shore - no surface patrol, however.

The large amount of boats deployed in the areas mentioned was not according to the original plan, but resulted from the necessity of allocating areas accessible to boats with a small amount of fuel, after the break-down of tankers. For the time being a further occupation of this area appears pointless - an eventual occupation will be necessary to link up the defence forces there.

Capetown - Madagascar area:

Deployed:	U 177	Lost:	-
	178		-
	181		-
	196		-
	197		197
	198		-

Successes:	U 177	7 ships	45,000 GRT
	178	6 ships	30,000 GRT
	181	10 ships	44,500 GRT
	196	3 ships	26,000 GRT
	198	7 ships	42,500 GRT
	197	3 ships	25,000 GRT

Situation: The South African coast and the Madagascar area as far as Mauritius have proved the most successful operations areas recently. Apart from coastal convoy traffic, isolated traffic in open sea was encountered on the following route: KP 80, KQ 80, 60, KR 10, KF 90 and KG 50.

While there has been absolutely no defence in open waters, medium to heavy aircraft activity was experienced everywhere in South African coastal waters.

The boat reported particularly heavy continuous air activity in the area from Lourenco Marques to Durban. Strong air activity was also reported on the Portuguese - East African coast off, and north of Mozambique.

All boats are at present on the return passage. Another occupation will follow as soon as possible.

Final summary:

a) U-boat operations in Mid-Atlantic area had to be abandoned considerably earlier than anticipated owing to lack of supply facilities.

It was intended to adequately supply the boats on the outward passage, far to the south. This plan was frustrated however, by

- 144 -

			the loss of the U-boat tanker U 463 in May, of U 487 in July and by the premature return of U 462 from the Biscay area owing to bomb damage.
			The deployment of several type IXc boats for the purposes of supply made possible the replenishment of a few boats.
			An adequate supplying on the return passage, and at supply points in the vicinity of the various operations areas, was intended as substitute for lack of replenishment on the outward passage.
			To be supplied: by U 459, all boats in Caribbean in DE 50,
			by U 462, all boats between Trinidad and Natal in EH 20.
			U 461 is reserve boat.
			This plan also failed as a result of the falling out of the tankers U 459, U 461, U 462 and later U 489. All operational boats therefore, received instructions to begin the return passage according to the state of fuel and provisions as no replenishment could be expected.
			b) The restricting of our "operational time" showed very unsatisfactory results: Experience of the last few years has shown that in the southern operational areas almost every boat has only one chance of attack and success - i.e. when it intercepts a convoy. The traffic conditions experienced and the extent of the operations areas allocated to the boats, make the chances slight and it is often not provided until after a 4 to 5 week wait and search. The limiting of the operational time to under 3 weeks means then that many boats will lose their only chance of success.
			c) Attempts by several boats to intercept traffic close to the main harbors and in the various passages of the Caribbean, had, for the most part to be abandoned after a few days, owing to the numerous enemy aircraft well equipped with radar. Confirmation of the boats led to intense and continuous enemy air activity, also probably to the by-passing of the traffic round the given U-boat positions.
			A typical example of this was the unsuccessful attempt to intercept the Freetown - Lagos coastal traffic.
			It is presumed that the "Metox" radiation was extensively exploited by the enemy for discovery and surprise attack on boats and this contributed largely to the high losses. (The reports of several boats of the approach of enemy aircraft at night without previous confirmation by radar).
			The cause of losses having been ascertained and temporarily overcome by the introduction of the new radar interception gear it will be possible to resume warfare under these conditions - only with VIIc boats in as far as supply facilities are available.
		II.	As already stated in KTB of 5.8., the deployment of U-boats in the southern operational area has on the whole not produced the expected results, however, unexpectedly high losses. The planning of this deployment left the command no other alternative but to occupy the area. Events during the month of May showed that it was not possible to continue the fight in the North Atlantic, owing to the excessive losses.

- 145 -

			If U-boat warfare was to be continued at all until the introduction of new weapons and apparatus, deployment of all outward bound VIIc and IXc boats could only take place in the areas mentioned. Warfare in this area had to be abandoned sooner than anticipated. Even if the success achieved appears proportionally slight compared with the losses it must be stressed that U-boat deployment lead to strong combination of the defence forces in the entire mid-Atlantic area and greatly taxed the strength of the enemy air forces. In this way the operational objective - the momentary use of U-boat forces for defence purposes - was achieved, even if the sacrifice was great.
			All boats arriving in this area in future are to be equipped with new Fu.M.B. (Hagenuk) and anti-aircraft armament reinforcements (quadruple and twin-mounted guns). The use of the Hagenuk anti-radar device will complicate the location of U-boats by the enemy, lessen the danger of surprise air attacks and facilitate more mobile night operations.

	On Return Passage: U 66 - 86 - 129 - 134 - 172 - 177 - 181 - 185 - 196 - 198 - 230 - 257 - 262 - 333 - 340 - 358 - 382 - 406 - 415 - 445 - 566 - 571 - 600 - 618 - 634 - 653 - 732 - 757 - 760.
	Entered Port: U 732 - Brest; U 333 - La Pallice.
	Sailed: U 229 - 341 - La Pallice; U 666 - St. Nazaire; U 389 - 419 - Kiel.

II.	Air Reconnaissance: Fighter penetration of outer Biscay area.

III.	Reports on the Enemy:
	a)	U 621 sighted aircraft in BE 5846, no attack.
	b)	None.
	c)	1)	English unit located in BE 5860.
		2)	U-boat sightings: BF 8262, CA 8224, AT 8422 and 3 sightings in unknown positions.
	d)	None.

IV.	Current Operations:
	a) -	b)	None.
	c)	1)	U 161 proposes EK 3755 as meeting place for the handing over of remaining fuel supplies from U 198, for 1000 on 3.9.
		2)	According to aircraft and radar observations the "Piening" route is again free of enemy U-boat chaser forces. This route is again free for returning boats.

	d)	1)	According to U 508's report of 30.8. supplies were taken on board from U 847 on 27.8. U 185 did not arrive until then. Apart from this U 508 heard heavy explosions on arrival. U 847 and U 185 were requested to send a position report without results, and the loss of these boats must be presumed.
			The explosions heard by U 508 probably tie up with the destruction of U 847, possibly though, only with the loss of U 185. Since the meeting of U 185 with U 172 in FD 2763 on 12.8. there has been no information as to the fate of U 185. U 185 had a section of U 604's crew on board.
		2)	U 403 had the operations area off Dakar. The boat did not report in spite of repeated requests. Last W/T message was passage report from BE 8416 on 23.7. According to Radio Intelligence report a steamer was chased and attacked by a U-boat in EK 4346 on 17.8. Shortly afterwards an aircraft sighted a periscope in EK 4640.
			As there was no other U-boat in this area, this can only refer to U 403. Otherwise no details. Loss must be presumed.

V.	Reports of Success: None.

Operational Order "Panama Canal" for U 214.

I.	Task: Mining operations are to take place off the Panama Canal.

II.	Enemy Situation: According to information received, the monthly total of traffic to and from the Panama Canal amounts to 140 ships. This is partly isolated traffic, after the appearance of U-boats, however, mainly escorted convoys.
	The directions are:
		Colon - Windward Passage
		Colon - Mona Passage
		Colon - Aruba - Curacao - Trinidad (about 10 sea miles North of the Islands)
		and reversed.

III.	Defence situation: Colon the naval and air base - strong air patrol is to be expected day and night also shore and air radar. Coco-Solo (East of Colon) is an American U-boat base. U 159 and U 161 reported the following in June and July 1942 from the area off the Panama Canal:
	1)	Put out and general course north south from Colon irregular deviating courses to the west.
	2)	Daylight traffic with air escort, single vessels and small destroyer escorts.
	3)	All kinds of air activity over the sea area, aircraft inexperienced.
	4)	Surface escort had good Asdic, not persistent, quickly lost, good water layers. In general 1 - 2 MTBs among the patrol craft off the entrance.
	5)	Colon lights burning, recognition probably altered, at night strong search lights every half hour.
	6)	Good hydrophone conditions.

IV.	Mining Gear:
	1)	15 SMA (shaft mines A) with 400 meters of anchor rope, time setting = 80 days, safety device time setting 3 hours, clockwork setting = 24 hours. Depth setting minus 15 meters, mine fitting tally 1. Mines may only be laid at a depth of 50 to 350 meters. Distance apart at least 400 meters.
	2)	6 EMS (periscope mine) setting for self sinking - after 72 hours.

V.	Geographical boundary: None. The mines are to be laid as near as possible to Colon, considering the 50 meter limit.

VI.	Execution:
	1)	Putting out according to Operations Order.
	2)	The mines are to be laid singly - if possible during the new moon period, in the section drawn on the diagram. The sketch

		provided is to be taken as an indication of the scheme for the operation.
	3)	The Commander may dispose the mines differently, according to the enemy situation observed. The time of mine laying is also left to the discretion of the Commander after a sizing up of the area.
	4)	Of the 6 EMS, 2 are to be laid to the west, and 2 to the east of the mined area. In this connection it must be remembered that:
		a)	The current in this area runs mainly to the east to northeast, with a speed of 1 - 1.5 knots.
		b)	The mine is active 10 minutes after being laid.
		c)	Mines ready for laying are to be handled with extreme caution, rubber horns are very sensitive.
		The laying of the remaining mines are to be carried out according to W/T orders.

VII.	Report: is to be made in a short signal as soon as possible after the execution of the operation - from a distance of not less than 150 sea miles, however, AFKP = have carried out minelaying off the Panama Canal.

VIII.	No restrictions in torpedo warfare.

IX.	If the operation cannot be carried out owing to enemy activity, withdraw and report by W/T to obtain directions for another minelaying area.

X.	After the mines have been laid, further orders for deployment will be sent by W/T.
