and two brigades of the Beauman Division had got south of the river, with thousands of lines-of-communication troops but only the 157th Infantry Brigade, 52nd (Lowland) Division was in contact with the Germans, occupying successive defensive positions. The French armies were forced into divergent retreats, with no obvious front line. On 12 June, Weygand had recommended that the French government seek an armistice, which led to an abortive plan to create a defensive zone in Brittany. On 14 June, Brooke was able to prevent the rest of the 52nd (Lowland) Division being sent to join the 157th Infantry Brigade Group and during the night Brooke was told 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, to withdraw towards Cherbourg. The rest of the 52nd (Lowland) Division was ordered back to a line near Cherbourg to cover the evacuation on 15 June.

The attacked the evacuation ships and on 17 June, sank the troopship in the Loire estuary. About and crew were saved but thousands of troops, RAF personnel and civilians were on board and at least died. Some equipment was embarked but ignorance about the progress of the German Army and alarmist reports, led some operations to be terminated early and much equipment needlessly was destroyed or left behind. About 700 tanks, 20,000 motor bikes, 45,000 cars and lorries, 880 field guns and 310 larger equipments, about 500 anti-aircraft guns, 850 anti-tank guns, 6,400 anti-tank rifles and 11,000 machine-guns were abandoned.
