'Mitten' was the British elimination of a small north-facing German salient in the area of Château de la Londe and Château de la Landel in northern France some 6 miles (10 km) to the north of Caen and so open the way for two brigades of Major General L. O. Lyne’s 59^th Division to pass through and take other villages (27/28 June 1944).

The task of clearing this area, comprising a few farms and the two large 18^th century manor houses (chateaux), was entrusted to Brigadier E. E. E. Cass’s 8^th Brigade of Major General L. G. Whistler’s 3^rd Division, a formation of Lieutenant General J. T. Crocker’s I Corps within Lieutenant General Sir Miles Dempsey’s 2^nd Army.

The initial evening assault, by the 1/South Lancashire, was repulsed, but during the morning of the following day larger attacks by all three of the brigade’s battalions (1/Suffolk, 2/East Yorkshire and 1/South Lancashire), with significant armour and artillery support, reached and took the intended objectives and in the process destroyed several German tanks. 'Mitten' cost at least three British tanks and, had it succeeded more quickly, Brigadier A. D. G. Orr’s 9^th Brigade, supported by Brigadier D. G. Cunningham’s Canadian 9^th Brigade detached from Major General R. F. L. Keller’s Canadian 3^rd Division, would have launched 'Aberlour' to take the villages of La Bijude, Epron, Galmache, St Contest, Authie and Cussy, but this follow-up operation was cancelled by Crocker.
