Robertson's June 5–15 leave (see June 3) falls inside this gap. A telegram he sent the Lord Chamberlain on June 8 fixes the day: he was to be at Buckingham Palace at ten o'clock on Wednesday the 13th for his Military Cross investiture. A
theatre ticket kept from that same evening puts him at the Comedy Theatre a few hours later. He put up first at the
Regent Palace Hotel by Piccadilly Circus, then moved to the
Savoy. The day after the ceremony he bought himself a
Military Cross brooch on Regent Street and was
initiated into Freemasonry at the Streatham Hill Lodge,
put up for it the previous February by two of the Allen family, and told that March, in a letter about his wound, that the Lodge was expecting him. The McGill Daily, October 8, 1917, reports: "Lieuts. E.P.
Fetherstonhaugh, Sci. '98, and A.M. Robertson, Sci. '16, of the Canadian Engineers, were invested with the Military Cross at Buckingham Palace in June." (See the
telegram.)
