In 1909, a Canadian military training camp named "Camp Sewell" was established 10 kilometers west of Carberry, south of the Canadian Pacific Railway line. It started out as a city of tents and covered a large area. The name of the camp was changed in 1915 to "Camp Hughes" in honour of Major-General Sir Sam Hughes, Canada's Minister of Militia and Defence at the time. Extensive trench systems, grenade and rifle ranges, and military structures were built at Camp Hughes between 1915 and 1916, and a variety of retail stores and entertainment complexes on a double-avenued area close to the main camp formed a lively commercial midway. During World War I, more than 38,000 troops of the Canadian Expeditionary Force trained at the camp, and by 1916 it had grown to such a large size that it had the largest population of any city in the province of Manitoba outside of the capital city, Winnipeg. Many of the soldiers who trained at Camp Hughes were later involved in the Battle of Vimy Ridge in France on April 9, 1917.
