With the forward German defenses crushed, the Soviets introduce their armor, the 5th Guards Tank Army pouring into the rear of the 1st Panzer.

Italy

The battle on the Volturno goes on. The American 5th Army continues to advance, especially on their right. The British 56th Div crosses the river east of its previous position and also pushes forward joining up with other 5th Army units which are trying to advance on to the ridge that divides them from the Rapido and Garigliano Rivers.

North of the Volturno Gen Hans Hube's German XIV Pzr Corps has established 3 fortified defensive lines: the so-called 'Barbara' line which goes from Monte Massico to the Matese hills by way of Teano and Presenzano: the 'Bernhard' ('Reinhard') line, much longer and stronger, consisting of a broad strip of fortified strongholds, from the mouth of the Garigliano to Castel di Sangro, relying on the natural defenses of the mountains, Difensa, Maggiore and Camino in the area between Presenzano and Sant' Ambrogio, and Monte Sammucro west of Venafro; and lastly, further north, the 'Gustav' line, the most solid of the 3 defensive lines, which follows the Garigliano and Rapido Rivers and takes in the natural fortification provided by Monte Cassino, then turning north through Roccaraso and Casoli to finish on the Adriatic coast south of San Vito. Behind these lines stands Gen von Vietinghoff's 10th Army, with Gen Hube's XIV Pzr Corps to the south and Gen Trangott Herr's LXXI Pzr Corps to the north.
