[i] Correct place-name spelling is Camblain-l’Abbé.

[ii] Private Laird died at the Devereux Mansion Hospital in Marblehead, Massachusetts on April 8th, 1920 from a combination of endocarditis, aortic insufficiency, and mitral insufficiency. The death certificate indicates that a contributory factor was arthritis experienced over 3 years and that this disease was contracted in France.

[iii] Headquarters details probably refers to signallers, runners, and administrative non-commissioned officers and other ranks.

[iv] There is a discrepancy between the 18th and the 4th C.I.B. war diaries. The 4th C.I.B. diary relates that at 12.45 p.m.: “Hostile shelling of BOUVIGNY HUTS with 5.9 [inch] shells. First shell to arrive hit men’s hut causing casualties to the extent of 5 Killed, 37 wounded.” From research, it appears that four soldiers are confirmed killed by the shelling with a possible five soldier deaths possibly related to this event. This would indicate the 18th Battalion’s War Diary is correct and the discrepancies between the diaries is unknown.

[v] The CWGC and service records indicated that Lt. Jarvis died July 20, 1917. Pte. A.A. McLeod, reg. no. 158645, was killed in action with no specific cause give. On the July 20, 1917, the casualties, including Lt. Jarvis amounted to four men in totally. Perhaps the War Diary was counting two men form men from the night of July 19/20 and the day of July 20?

[vi] Lt. Dougall was to rise from the ranks from Private to Lieutenant. He earned the Military Cross, Medaille Militaire (France) and died at the age of 19 on August 19, 1917, just one month after this diary entry.
