Like the Churchill-I, the IV had the ability to cross very wide trenches and shell craters. It had also a redesigned turret of cast armor combined with welded armor plate. This tank carried the 61b anti-tank gun and good enough to deal with Pz III-series used by the Germans.
Japanese troops entered Manila.

First Allied attacks on Monte Cassino. The battle raged from 12 January till 18 May with heavy Allied losses.
Allied Forces resume attacks at the run aground Italian front.
Cassino formed the focal point of the Gustav Line, the strongest German defences south of Rome. A natural fortress consisting of a town on the slopes of a high mountain crowned by Benedictine Monastery and skirted to the south by three rivers, Cassino had to be captured by the Allies in order to gain access to the Liri Valley, the so-called 'gateway to Rome.' The battle raged from 17 January until 18 May, often in appalling wet and cold weather with heavy Allied losses. Eventually, the Germans evacuated the town, and the monastery was finally stormed by Polish troops.
Operation 'Bodenplatte'. In Europe Allied air forces operating from airfields in Holland, Belgium and northern France are surprised by a sudden attack by more than 800 diverse aircraft which the Luftwaffe has assembled from all possible locations, despite their loss of 50 many in recent weeks. The motley collection is flown by novices who are led to their targets by the few remaining skilled pilots. The Allies lose 300 aircraft but can replace these quickly; the Luftwaffe count is just over 200. These, and their pilots, are irreplaceable and the action has rendered the Luftwaffe almost powerless in the west.
