Allied Command

Before leaving for Hawaii for discussions with Nimitz and MacArthur on the Pacific war strategy, Roosevelt replies to Chiang Kai-shek's letter of July 8, agreeing to send him a personal political representative and asking him in the meanwhile to entrust the command of the Chinese army to Gen Stilwell.

Eastern Front

After several days of fierce street fighting the 3rd Belorussian Front captures Vilna, the capital of Lithuania. The German Army Group North is in still greater danger of being completely cut off. Red Army elements in Poland, after capturing Kaunas and Grodno, are now within 100 miles of the German frontier.

After a fierce battle the 5th Army takes Vilnius, more than 7,000 of the 15,000 strong garrison having fallen during the fighting. The 11th Guards Army crosses the Niemen River at Alytus. German counter-attacks are beaten off with some difficulty.

Koniev launches his offensive without arty preparation. The 60th and 38th Armies attack the center and right of Hauffe's XIII Corps near Brody. Simultaneously the 13th Army begins a furious attack against the left wing of the XIII Corps and break through near Radekhov. Soon after the 38th Army breaks through near Zolochev. On either flank of the assault the XLVI and XLVIII Panzer Corps counterattack but are hit by the 3rd Guards and 1st Guards Armies.

Italy

The American 34th Div of IV Corps advances about 3 miles toward Leghorn. The other 2 divisions in the American IV Corps, the 88th and 89th(?), are engaged in the central and right sectors. The 4th Mountain Div of the French Expeditionary Corps captures San Gimignano, while another French division, the 2nd Moroccan, gets nearly as far as Poggibonsi and the suburbs of Castellina in Chianti about 20 miles south of Florence and halfway between Arezzo and Leghorn.

In the center of the Allied line the New Zealand 2nd Div captures the summit of Monte Castiglione Maggiore.

New Guinea

On Numfoor Island the 503rd Parachute Infantry makes contact with the main body of Japanese who are still holding out about three miles northeast of Namber airfield.

On the mainland, in the Aitape sector, US units counterattack. Supported by artillery, the 124th Infantry Regiment (31st Infantry Division), the 112th Cavalry, and the 127th and 128th Infantry Regiments (32nd Infantry Division) advance against the enemy and succeed in reaching the Driniumor River at two points. 5th Air Force supports the attack with air strikes and aerial resupply of troops in heavy jungle. The 128th Infantry routs the Japanese coastal attack group, destroying most of its guns.

Pacific

• The US submarine Herring (SS-233) is reported as presumed lost in the Pacific Ocean area.

Secret War

With a crew who had completed only 100 hours of flying, the pilot of a Ju-88G night-fighter lands by mistake at Woodbridge, Suffolk. The aircraft is fitted with the Lichtenstein SN-2 wide-angle radar which has so benefited German night-fighter techniques for many months. Its capture robs the German night-fighters of their last chance to defend the country against Allied raids because British experts quickly issue instructions which nullify its value.

Western Front

The American 4th Arm Div lands in northern France. General Headquarters of the US 1st Army approves plans for Operation COBRA, the attack on St Lô.

The American VIII Corps continues to push south, but in the VII Corps sector only the 9th Div, on the left flank, makes headway, while action on the rest of the line is virtually suspended. The US XIX Corps continues the hard struggle for St Lô. Finally, in the V Corps sector, the 5th Div goes into the line to replace the 1st Div, which is moved to Colombières, some 6 miles southeast of Isigny, before going over to the VII Corps sector.
