In the Globe and Mail, Jack Granatstein remembers many occasions where individual Canadians have chosen to get involved in other peoples’ wars:
Some historical perspective might suggest that Canadians serving in foreign armies is not new to our times. Many Canadians served in the U.S. Army during the Civil War, fighting for the Union and against slavery. Upward of 50,000 Canadians are estimated to have enlisted in the Union forces, and a few hundred wore Confederate grey. Union recruiters operated openly in the Canadas during the war, and many Canadians went south to join up. Even Calixa Lavallée, the composer of O Canada, served as a Union officer. No one objected strenuously.
A few years later, Bishop Ignace Bourget and the Roman Catholic Church in Quebec raised troops to help defend the Papal States against the forces seeking unification of Italy. More than 500 well-educated francophones enlisted in the Papal Zouaves, ready to sail to Italy to defend the Vatican’s territory. Not all the Zouaves made it to Rome by the time the struggle ended in 1870, but eight died. Once again there were few complaints, although Protestants were surely annoyed at this ultramontane Catholic fervour.
In the 1930s, the Spanish Civil War pitted General Francisco Franco’s Nationalists against the Republican government of Spain. Hitler’s Germany and Mussolini’s Italy supported the Nationalists. The Soviet Union backed the Republicans; so did at least 1,300 Canadians who volunteered to fight against fascism and went to Spain to serve in what went on to become the Mackenzie-Papineau Battalion, while another 300 fought in the American Abraham Lincoln Brigade.
The worry about today’s Canadians-fighting-in-foreign-wars revolves primarily around young Muslim men going abroad to fight religious wars. Thus far, few of them have come back to Canada with an obvious intent to bring the war back with them:
None of those war veterans brought jihad home to Canada, a legitimate concern we live with today, although some communists who fought in Spain might have had attitudes inimical to the Canadian capitalist state. Most of the Islamist volunteers, if they survive to return to Canada, will likely settle down to a “normal” life. But so long as ideology, religion, adventurism and a soldier’s pay still matter, Canadians will likely continue going off to fight in other people’s wars.
