Where do the maps come from ? All about how they came to McMaster University here
McMaster University Library is home to one of the largest collections of World War I trench maps in the country after acquiring a significant collection from Dr. Peter Chasseaud, the world’s leading expert in First World War military maps.
The acquisition of more than 900 maps will triple the Library’s trench map collection.
Chasseaud has been building his collection in the UK since 1964. Now, thanks to funding from the Movable Cultural Property Grants Program on behalf of the Honorable James Moore, Minister of Canadian Heritage and Official Languages, the maps will soon have a Canadian home, providing a significant resource for those interested in Canada’s participation in the Great War.
Many of these maps, originally produced by the British Ordnance Survey, were the only maps available to the Canadian Forces during World War I, covering areas and actions of historical Canadian significance such as “Preparation for Battle of Arras, Vimy, March 1917” and “Cambrai Battlefield – North: Final Advance 1918”.

A series of leaflets, directed at women in Canada and Britain during the First World War, provides insights into both the British and Canadian governments’ efforts to actively involve women in the struggle for victory.
Pilgrimages to the sites of First World War battles by veterans and the bereaved began immediately after the war’s conclusion and continued throughout the 1920s and 1930s. McMaster’s small collection, consisting of a telegram, programmes, menus, newspapers, post cards, and a commemorative medal, relates to the inaugural pilgrimage to the Vimy Ridge Memorial in 1936.
