Reading a Canadian Army War Diary from the Second World War

War diaries are the written records completed by officers of a unit for historical or record-keeping purposes. Typically, Canadian infantry battalions made the intelligence officer responsible for writing these documents. Diary entries were meant to be completed daily but there were occasions when these officers did not find time to complete their entries on a regular basis. It was possible for these documents to be written after the fact based on notes taken at the time or the memory of the diarist and his fellow soldiers. Diary entries could also be lost during combat, leaving gaps in the written record. The Stormont, Dundas and Glengarry Highlanders war diary for the 6 June to 17 June 1944 period appears to be complete and written on a daily basis excepting when the diarist indicates otherwise.

Reading Canadian Army war diaries can be tricky. Here are some tips to help you.

Times are given in a 24-hour clock format. Times in the AM will have a 0 at the beginning of a four-digit sequence. Times in the PM will continue counting upwards to 2359 hours (or just before midnight). If you see a time like 2100 hours, the easy way to convert it to our 12-hour clock is to subtract 12 from the first two numbers.

Example (2100 hours): 21 – 12 = 9 = 9:00 PM

Diarists typically capitalized the locations they mentioned. For example, BENY-SUR-MER and GRUCHY are villages in Normandy. In addition to or instead of mentioning local villages and towns, diarists often provided their location as a 9-number grid reference which corresponds to locations on the maps issued to the unit. Sometimes the number appears as only 4-digits. This reference will be based on the same maps, but the extra numbers make the location more precise.

Example: Reference 994848 can be reduced to Area 9984, which corresponds to the first, second, fourth, and fifth numbers in the 9-figure sequence.

It is common for diarists to make errors in their entries. Sometimes these errors were caught and struck through on the typewriter with multiple X’s. Other times, officers went through and crossed out mistakes while making notes in the margins. You may find errors in spacing or spelling but these are all reproduced faithfully on Project44.ca.
