On the 7th of June, 1944, SS Panzergrenadierregiment headquarters, led by the SS SS and Kart Meyer belonging to the 12th SS Panzer-Division Hitlerjugend counterattack towards the beaches and settled in the abbey in order to take advantage of the point of view offered by constructions. Indeed, from this position, the Germans can observe a large part of the adverse movements in the sector and Kurt “Panzer” Meyer directs his counter-attack which pushes back the Canadians of the 9th brigade of the 3rd infantry division, supported by the Tanks of the 27th armored regiment Sherbrooke Fusilier, at the height of Buron. S.S. soldiers, determined not to retreat hold this position for a full month. Several Canadian soldiers are taken prisoner during this period and are questioned in the abbey domain. The fighting, particularly violent in this sector, led the soldiers to carry out acts of extreme savagery: within a week of disembarkation, 27 Canadians were coldly executed near the abbey.
