a) All Japanese resistance on Attu, Aleutian Islands ceased.

c) French Resistance saboteurs destroyed 300 tons of tires in the Michelin factory at Clermont-Ferrant.
d) The first fruits of victory reached British shops in the form of Algerian wine.
From B.d.U.:
a) It is intended that U 575 and U 731 shall proceed in company through Biscay. The following basic order has been issued. As far as possible 2-4 boats are to make the return passage through Biscay in company.
Commanding Officers will agree at the rendezvous on details of procedure for the return passage.
The basis is to be:
1) Proceed in accordance with B.d.U. Standing Order No. 13.
2) Remain surfaced as long as possible in good weather in order to cover ground.
3) In case of a surprise attack, remain on the surface. Fire from all guns.
4) Keep together at all costs.
b) U 178 (IXD2; KrvKpt. Wilhelm Dommes) reported: As convoys proceed close inshore, it is possible to haul ahead without maintaining close contact, if the boat remains at least 60 miles off the coast. Boat will not then be subject to interference by a/c, even though Radar locations constantly intercepted. The enemy is using a large number of a/c, which patrol the area ahead and to seaward of the convoy. At times 3 a/c were sighted at one time by day as far as 50 miles off the coast. Boat succeeded in getting away on the surface.
c) U 119 (XB; Kptlt. Horst-Tessen von Kameke) has carried out the minelaying operation off Halifax as ordered.
d) U 304 (Oblt. Heinz Koch) last made a short weather report on 24.5. from BD 23. On the same day she was ordered to an attack area in AK 4675, depth 70 miles. Since 1.6. the boat has several times been ordered to give her position and no answer has been received. As there are no clues, she must be presumed lost.
B-Dienst Report:
a) Radio intercept from the RAF: The months of April and May have resultated in the destruction of the German Uboat Arm, with 43 Uboats sunk during the month of May alone. This became possible with the arrival of the Escort Carriers as of the month of March.
2316 - Sundown. Weather and Sea unchanged in 3 days and 7.5h.
