Air Operations, Marianas

In the opening move of the Battle of the Philippine Sea, 9 Yap-based G4M 'Betty' bombers searching for Task Force 58 miss that target but instead locate a Fifth Fleet escort carrier group southeast of Saipan.

Battle of the Atlantic

U-767 is located by D/F by the 14th Escort Group comprising HMS Fame, Hotspur, Inconstant, Icarus and Havelock. Fame attacks first with Hedgehog and soon hears 3 explosions which in effect ended the U-boat. Attacks by the other ships are carried out, but the first attack did the job.

Battle of the Philippine Sea

The US forces make their rendezvous west of the Marianas while the Japanese continue to approach. The Japanese are heavily outnumbered by US Task Force 58, which includes 7 battleships, 14 carriers (7 heavy), 21 cruisers, and 69 destroyers. Late in the evening the Japanese scout planes sight the American fleet. This is the only advantage that the Japanese have and comes about principally because their scout planes have a longer range. The Japanese plan to launch their strike planes early the next day while still at very long range and, after attacking, to have them fly on to Guam where the local forces can protect them while they refuel and rearm. Once this is done they can attack again on the return journey. The glaring weakness in this plan is that the air forces on Guam have suffered seriously from American attacks recently and have failed to inform the fleet of this. In fact this shortcoming is less significant that might have been the case as the American ships exact such a heavy price from the first attacks.

CBI

The New Galahad Force cuts the Mainga Ferry Road, the main supply route for the Japanese defending Myitkyina.

China

Japanese troops of the 11th army capture the cities of Chuchow and Changsha, 322 km south of Hankow.

Eastern Front

The Leningrad front breaks through the main Finnish positions on the Mannerheim line and advance toward Viipuri.

Italy

Units of the 1st Motorized Div of the French Expeditionary Corps under Gen Alphonse Juin reach Radicofani, northwest of Orvieto, overlooking the road frm Florence to Rome.

In the British sector the columns converging on Perugia meet with a certain resistance in the outskirts of the city. During the night the Germans abandon Città della Pieve, which is occupied by British XIII Corps units. The 8th Army captures Assisi, south of Perugia.

Marianas

The advance of the 4th Marine Div reaches the west side of Saipan at Magicienne Bay. The Japanese forces are thus separated into two. Parts of the 27th Div on the right of the 4th Marines, captures Aslito airfield. Japanese air strikes sink 1 destroyer and 2 tankers offshore as well as damaging the escort carrier Fanshaw Bay (CVE-70). Much of the air cover and close support has been withdrawn to prepare to take part in the imminent fleet battle although the guns of the US Navy and landing craft prevent the Japanese from bringing reinforcements up against the Tanapag Harbor beachhead, north of the harbor itself. Taking advantage of the absence of American aircraft, Japanese air forces attack American shipping and beachheads, losing about 20 aircraft by anti-aircraft fire.

New Guinea

A fresh US regiment is deployed in Biak Island, where the Americans are getting ready to launch a determined attack to liberate the Mokmer airfield area. Gen Walter Kreuger orders the forces in the Wadke-Sarmi area to resume the offensive to the west of the Tirfoam River line.

Pacific

• The US destroyer Phelps (DD-360), along with infantry landing craft (gunboat) LCI(G) and amphibian tractors LVT(A), oppose between 25 and 30 Japanese landing barges, southward-bound off Garipan, Saipan, sinking 13 and putting the rest to flight.
• The US motor torpedo boats PT-63 and PT-107 are destroyed by fire off New Ireland.
• The British submarine Storm attacks a Japanese convoy off Penang, Malaya and sinks the gunboat Eiko Maru (3011t).

Southwest Pacific

In response to a Combined Chiefs of Staff query on the possibility of bypassing the Philppines and the Palaus to attack Formosa or attack the Japanese home island of Kyushu directly, Gen MacArthur declares these options as unsupportable logistically. He states the Philippines are absolutely necessary as a base of operations for either Formosa or Kyushu. In addition, he repeats the contention on that America has a moral obligation to return to the Philippines.

Western Front

The Commander-in-Chief of the 21st Army Group, Gen Montgomery, issues his first written instructions since the landing in Normandy. He calls for the capture of Caen and Cherbourg. On the Cherbourg front the American VII Corps begins its advance on the city with the 9th, 79th and 4th Divs operating left, center and right respectively of the line.

The situation in the St Lô sector is unchanged, with the XIX Corps held up north of the town.
