Lieutenant Colonel H.L. Milligan, D.S.O.
18th (Western Ontario) Battalion
I met Colonel Milligan recently, and am advised that he is not physically fit to return to his duties, and have lost his wife and daughter in the last few months, I hope you will grant him this extension of leave.
(J.E. Armstrong to militia minister, 18 Jan 1917)
