UNITED KINGDOM: In England, the principle of coordinated day and night bombing receives its first formal definition in the "Joint British/American Directive on Day Bomber Operations involving Fighter Cooperation." The emphasis is placed on achieving continuity in the bombing offensive from the UK.

 The US Eighth Air Force flies Mission 3; 11 B-17 Flying Fortresses bomb Longeau marshalling yard at Amiens, France at 1801 hours without loss.

Combined Ops HQ: The Allied reconquest of Europe must begin with a soldier wading ashore out of the sea. The question to be answered after the Dieppe raid is: How do you get him ashore and ready for battle when the enemy is sitting up there with a battery of guns trained on him?

Lord Mountbatten, the chief of Combined Operations, believes that Dieppe shows the need for overwhelming fire support, including close support, during the initial stages of an attack. Dieppe has convinced Allied planners that the massive force needed to open a second front cannot be assembled before 1944 at the earliest.

The entire West Coast is ordered to dim city lights at night. Searchlights crisscrossing the sky at Hollywood movie premieres are extinguished for the duration. Limits have also been placed on movies studios relating to the amount of cloth they could use in costumes, the quantity of new construction they could devote to sets, and the amount of film stock they could purchase. Hollywood directors must learn to limit the number of "takes" when filming movies.

ATLANTIC OCEAN: The German submarine U-464 is sunk southeast of ICELAND at 61.25N, 14.40W by a USN PBY-5A Catalina of Patrol Squadron Seventy Three (VP-73) based at Reykjavik, Iceland. While on convoy escort in Skerja Fjord near Reykjavik, the PBY crew surprised the surfaced submarine in rough weather and attacked with 5 depth charges which disabled the sub and prevented it from diving. Although U-464 could make 8 knots on the surface, the crew realized that the boat would be destroyed by nearby surface forces so the U-boat captain decided to scuttle the boat and got underway heading for a nearby Icelandic trawler. There are two versions of what happened next. The British and Icelandic versions are that the Icelandic trawler Skaftfellingur headed for the sinking U-boat and commenced rescue operations. The Germans seemed hesitant to leave their boat but finally after one of them had been pulled over to the trawler via line they jumped into the water. The 7-man Icelandic crew then accommodated the 52 German survivors and placed them in the bow. A machine gun on the bridge enforced the order. Later the same day 2 British destroyers arrived and captured the Germans. The German version is that the U-boat crew boarded the Icelandic boat and subdued its crew and headed for Germany and they were only interrupted by 2 British destroyers. The RN authorities believed the Icelandic version. Only 2 of the 54 crewman of the U-boat died. The Icelandic captain is interrogated by a British court in Fleetwood, Lancashire, about this.
   Returning to base, the PBY pilot sent the following message: Sank Sub Open Club.  This message was directed at Commander Daniel V Gallery, USN, who had closed the Officers Club because the PBY crews had not sunk any submarines. Gallery was in command of Task Group 22.3 which captured the German U-boat U-505 in the Atlantic on 4 June 1944. U-505 is currently on display in Chicago, Illinois.
