Historical Background:
After the failure of Operation Goodwood made by Montgomery on the east of Caen, General Bradley ordered to launch Operation Cobra to breakthrough the German front facing US troops. General Collins, commander of the VIIth US Army Corps had three infantry divisions plus one attached infantry regiment at his disposal for the attack. Operation Cobra began by a massive carpet bombing made by 1 485 heavy bombers on a limited area south of the road Periers to Saint-Lô. Most of the units depending of the Panzer Lehr Division which were under the bombing were destroyed. Then the US infantry units began to advance towards their objectives. In spite of the devastation, some German strong points had survived and opened fire on US troops. On the west flank, the 330th Infantry Regiment was quickly stopped by enemy fire near the road Periers to Saint-Lô. In the central area, the 9th Infantry Division advanced slowly towards Montreuil-sur-Lozon. At its left hand, the 4th Infantry Division was stopped at the surroundings of la Chapelle-en-Juger by the fire of surviving units of the Panzer Lehr Division. And on the east flank, the 30th Infantry division failed to capture the devastated village of Hebecrevon. Operation Cobra had a hard beginning.
