On 14 June, Brooke was able to prevent the rest of the 52nd (Lowland) Division being sent to join the 157th Infantry Brigade Group. During the night Brooke was informed that he was no longer under French command and must prepare to withdraw the British forces from France. Marshall-Cornwall was ordered to take command of all British forces under the Tenth Army as Norman Force and while continuing to co-operate, withdraw towards Cherbourg. The rest of the 52nd (Lowland) Division was ordered back to a defence line near Cherbourg to cover the evacuation on 15 June. The AASF was also directed to send the last bomber squadrons back to Britain and use the fighter squadrons to cover the evacuations. The German advance over the Seine had paused while bridges were built but the advance began again during the day, with the 157th Infantry Brigade Group engaged east of Conches-en-Ouche with the Tenth Army. The army was ordered to retreat to a line from Verneuil to Argentan and the Dives river, where the British took over an front either side of the Mortagne-au-Perche–Verneuil-sur-Avre road. German forces followed up quickly and on 16 June, the Tenth Army commander, General Robert Altmayer, ordered the army to retreat into the Brittany peninsula.
