Just as the 87th Battalion prepared to deploy to France in summer 1916, Reginald William Frost replaced Lieutenant Colonel I. P. Rexford in command. A native of Norfolk, England, Frost was born on 21 May 1885. He had served seven years with the 66th Princess Louise Fusiliers when he enlisted in the 14th Battalion under the command of Frank Meighen at the outbreak of the war.
