The fonds consists of a photocopy of Beach's typed copy of his report "Notes on the Battle of the Lake Trasimeno Line (1944). A statement on the covering page states "these have not been submitted to Higher Cmd for approval as some of the opinions expressed are unwise in the extreme." Also included is correspondence (photocopies of 2 typed letters in, together with photocopies of 2 replies) between William J. McAndrew, Directorate of History and Professor Beach (1986-87). The correspondence concerns the authorship of the report, as Beach's name was not attached to it, and questions about the activities of the 1st Canadian Armoured Brigade, which Beach served in.
