Operation Jupiter was an attack by VIII Corps of the British Second Army, on 10 July 1944. The objective of the 43rd (Wessex) Division was to capture the villages of Baron-sur-Odon, Fontaine-Étoupefour, Chateau de Fontaine and recapture Hill 112. An attached brigade of the 15th (Scottish) Division would take Éterville, Maltot and the ground up to the River Orne and then the tanks of the 4th Armoured Brigade, supported by infantry, would advance through the captured ground and secure several villages to the west of the River Orne. It was hoped that the initial objectives could be captured by 9:00 a.m., after which the 4th Armoured Brigade would begin the exploitation phase.
