July 23, 1944: Marshal von Kluge sees that the German forces are becoming exhausted in the Cotentin peninsula, so he requests Hitler’s authorization to carry out a strategic retreat of all the soldiers and vehicles in the west of Normandy. Hitler, having refused the majority of retreats since D-Day, finally accepts. The American forces continue their ‘punch’ operations to maintain the contact with the German soldiers and to observe the new positions taken by the enemy. The weather, still very bad, continues to delay the start of the Operation Cobra. The American troops are near Lessay and try to push in direction of Periers, continuing contact with the Germans. While continuing to prepare for the offensive, they mass towards the various points which will be used as departure points Operation Cobra. The American units receive new uniforms, helmets, and get rid of useless materials which could slow them down. General Bradley decides that the infantry needs to attack ahead of of the tanks in Operation Cobra, whereas Montgomery uses the opposite strategy.
The British reinforce their positions to the south of Caen, weakened by the losses of Operation Goodwood. The American High-Command is very critical of general Montgomery who is considered incompetent to lead in the east. Furthermore, the small amount of space controlled by the British and Canadian forces does not allow the creation of multiple runways, which seriously handicaps the Allied air forces at this stage of the Battle of Normandy. Eisenhower even proposes Montgomery’s dismissal to the English Prime Minister, Winston Churchill, which is ignored. This highlights the tension within the Allied forces.
After dark, a large group of British bombers attacked Kiel, Germany; the attack lasts through midnight. The German fighters summoned to intercept go after the decoy force rather than the main force.
Above France, US 8th Air Force attacks airfield with 243 bombers supported by 187 fighters.

RAF Bomber Command sends 60 aircraft to attack V-weapons sites during the day, 116 aircraft to attack V-weapons sites overnight, and 119 aircraft to attack Donges overnight.
On the eastern front, Soviet forces capture Pskov. This was the last major town of the prewar USSR to have been held by German forces. To the south, troops of the 1st Ukrainian Front enter Lublin. German forces continue to resist in Lublin.
In Italy, elements of the US 4th Corps (part of US 5th Army) penetrate the outskirts of Pisa but are only able to occupy the area south of the Arno River. British 8th Army captures Tavernelle. US 12th Air Force aircraft attack transportation lines, enemy positions, and other targets in support of ground operations as well as bridges over the Po River.
