In the third phase, "Impetigo", the 43rd Division would move forward to relieve all Scottish infantry north of the Odon. The 15th Division would then assemble across the river and expand the bridgehead by capturing several important villages. In the final phase, codenamed "Goitre", elements of the 43rd Division would cross the river to hold the area taken, while the 15th Division would continue to expand their bridgehead. The 11th Armoured Division would attempt to force a crossing over the River Orne and advance on their final objective of Bretteville-sur-Laize. The 4th Armoured Brigade, although attached to the 11th Armoured Division, was restricted to operations between the Odon and Orne to protect the Corps flank and to be in a position to attack westwards or towards Caen, as necessary.
