Eastern Front

Battles rage from the Sudeten Mountains to the Gulf of Stettin. In the area between Stettin and Schwedt Konstantin Rokossovsky's forces win a wide salient across the Oder, with its point on the Randow River. Farther south, Zhukov's troops press on north and south of Spremberg; the Russian 33rd Army inflicts heavy losses on the German 9th Army. South of Cottbus the 1st Ukraine Front breaks through the front of the 4th Panzer Army and advances across the Spree toward Berlin takin Calau. The Germans launch desperate counterattacks north and south of Frankfurt-on-the-Oder. Northwest of Frankfurt there is also furious fighting in the Sternebeck and Prötzel areas. In Czechoslovakia the Russians exert incessant pressure on the industrial district of Moravska-Ostrava (Ostrava) and on Brno.

GERMANY

The artillery of the 1st Belorussian Front is shelling Berlin's eastern suburbs. Juterbog, the main Wehrmacht armaments depot, is captured by the 4th Guards Tank Army. The 4th Panzer Army is being broken apart at Cottbus by the 5th Guards Army. The 2nd Belorussian Front (2nd Shock, 49th, 65th and 70th Armies) joins the offensive, its objective being to reach the Baltic and sever the Western Allied drive into Denmark. The defending 3rd Panzer Army is hit by artillery and aerial bombs but still defends stoutly. To date the Red Army has lost 2,800 tanks in the Berlin offensive.[MORE]

Italy

The US 5th Army comes down from the Apennines on to the Lombardy plain; the IV Corps reaches Casalecchio, in the neighborhood of Bologna, and the II Corps takes the region between Casalecchio and Gesso.

In the British 8th Army sector, the X Corps reches the Idice River, and the Polish II Corps and British XIII Corps establish bridgeheads over it. Gen Heinrich von Vietinghoff, Commander of the German Army Group C, order the German forces, the 10th and 14th Armies, to withdraw on to the line of the Po. But his decision is too late, for the Allied armored divisions are already hurling themselves on the German troops all along the line.

Okinawa

There is still savage fighting in front of the Shuri line, especially on the Kakazu Ridge, where the Japanese take heavy toll of the American tanks. The American units manage to make good progress in this sector, but have to withdraw during the night in the face of furious Japanese counterattacks.

The 6th Marine Div completes the mopping up of the Motobu peninsula.

Fighting continues on Ie Shima, where the 77th Div succeeds in surrounding the 'Pinnacle' in the Mount Iegusugu area, while in the south of the island it seizes a height that the Japanese are defending tenaciously, known to the Americans as 'Bloody Ridge'.

Off Okinawa the battleship Colorado (BB-45) is badly damaged by an accidental explosion, and the destroyer Ammen (DD-527) by a Japanese horizontal bomber.

Supported by Filipino guerrillas, the American infantrymen succeed in isolating over 8,500 enemy troops. The Americans have lost over 400 kiled and 1,700 wounded in the fight for Cebu, not including another 8,000 casualties as a result of disease. The Japanese have lost nearly 6,000 men.
