Air Operations, Europe

• 12 Venturas of 487 (New Zealand) Squadron are sent to attack a power station on the northern outskirts of Amsterdam. 1 of the planes returns early. The rest of the planes proceed with an escort of 3 squadrons of Spitfires. Unfortunately, an earlier Spitfire sweep has alerted the German defences while the Ventura force is still flying at low level over the North Sea. It is also unfortunate that an exceptional number of experienced German fighter pilots are present at Schiphol airfield for a conference. As a result, 69 German fighters are up in the air near Amsterdam when the Ventura force crosses the Dutch coast. Some of the German fighters go after the Spitfires while the remainder attacks the bombers. 9 Venturas are shot down before reaching the target and a tenth is badly damaged but it manages to turn back and reach England. The only remaining Ventura from the formation is that of Squadron Leader L. H. Trent, a New Zealander. His Ventura, completely alone, presses on to the target and bombs it. The bombs just miss but some blast damage is caused. This last Ventura is then immediately shot down. Squadron Leader Trent and his navigator are the only survivors and become prisoners of war. The story of this action, in which 10 out of 11 Venturas were shot down, was reconstructed after the war and Squadron Leader Trent was awarded the Victoria Cross in 1946.
• 6 Bostons successfully bomb the steelworks at Ijmuiden.

North Africa

The American 1st Div finally fights its way out of 'Mousetrap' Valley and captures Mateur, but the Germans manage to improvise a new defense line and the advance is halted. Meanwhile, there is also activity on the central and southern sectors of the front, scene of what may the final attacked.

Gen Alexander outlines his plan for the final attack to Gen Anderson. The IX Corps, with 2 infantry and 2 armored divisions, is to make the main effort, thrusting directly toward Tunis along the road from Medjez el Bab. A lightning attack is planned in order to split and destroy the enemy rather than compress his bridgehead, since the schedule for the invasion of Sicily requires a quick conclusion to North African operations.

In the US II Corps area, the 81st Armored Reconnaissance Battalion, followed by other elements of the 1st Armored Div, advances to Mateur as the enemy is withdrawing from it and quickly secures the town. The 34th Div moves eastward toward Chouïgui, making no contact with the enemy.
