As the LAC say, these dairies of the “Canadian Expeditionary Force (CEF) units were required to maintain a daily account of their "Actions in the Field." This log was called a War Diary.
This database contains the digitized War Diaries of CEF infantry, artillery and cavalry units, Brigade, Division and Corps commands and support units such as Railway and Forestry troops. The site also includes the War Diaries of the Royal Newfoundland Regiment and several British units that served under Canadian command.”
