From The Story of the 2/4th Oxfordshire and Buckinghamshire Light Infantry, by Captain G. K. Rose M.C. (Oxford: B.H. Blackwell, 1920)
On the night of March 15 the Brigade was relieved by the Warwicks. The Battalion moved back to Framerville, where Quartermaster’s Stores and Transport rejoined.
This could have been either the 2/7th or 2/6th Warwickshire Regiment. As both were part of the 182nd Brigade of the 61st (South Midlands) Division.
