For Canadian impressionist Mary Riter Hamilton, capturing the emotional landscape of battlefields and graveyards in the months after the Great War's armistice became an artistic calling and defined her work. A woman alone after the storm had passed, she found that her life after the war was indelibly marked by the experience. Undeterred by a rejection from the Canadian War Memorials Fund, who nominated only male war artists abroad, in 1919 Hamilton received a commission from the Amputation Club of British Columbia (now the War Amps) to commemorate those lost at war. She travelled from Victoria to the pre-reconstruction battlefields and towns of the Somme, Vimy Ridge, and the Ypres Salient where amid harsh conditions - inadequate shelter and food, surroundings littered with unexploded shells - she recorded with determination, pride, and grace the ruins of war. Based on intensive archival research in Canada, France, and Belgium, and using many previously unpublished letters, I Can Only Paint offers an insider's view of the artist's vast, underexplored body of war work and the conditions in which she created it. It places this period, central though it was, in the context of a full understanding of her life and restores the work she created there to its proper place in the canon of war art in Canada and abroad. Irene Gammel argues that Hamilton's work encoded a female perspective that distinguishes her paintings from the work of official Canadian war artists. The first reliable account of Hamilton's impressions of Canada's most haunting sites of conflict, I Can Only Paint captures with detail and sensitivity an experience that defined her life and recovers a body of work that stands as a unique and enduring portrait of the effects of the Great War.
