German forces crossed the Seine on 9 June, cutting off the 51st (Highland) Division north of the river, two days after 52nd (Lowland) Division had begun to land and the assembly point of the division was changed to Rennes in Brittany; the 157th Infantry Brigade, which had arrived first, was directed to Beaumont near Le Mans; the rest of the division to follow on. The 1st Canadian Infantry Brigade of the 1st Canadian Infantry Division began its arrival at Brest on 11 June and was sent to Sablé-sur-Sarthe, on the assumption that two fresh divisions would be enough to allow the Tenth Army to retreat through them and take up positions prepared around the Brest peninsula. That day, the Anglo-French Supreme War Council met at Briare and General Charles de Gaulle (minister of war) was sent to Rennes to survey progress on the redoubt; on 12 June, de Gaulle reported that Quimper would be a favourable place for the government to retreat to, since it would be easy to take ship to England or Africa; the prospect of maintaining a redoubt in Brittany was non-existent.
