The Battle of Duck Lake was an infantry skirmish 2.5 kilometres (1.6 mi) outside Duck Lake, Saskatchewan, between North-West Mounted Police forces of the Government of Canada, and the Métis militia of Louis Riel's newly established Provisional Government of Saskatchewan. The skirmish lasted approximately 30 minutes, after which Superintendent Leif Newry Fitzroy Crozier of the NWMP, his forces having endured fierce fire with twelve killed and eleven wounded, called for a general retreat. The battle is considered the initial engagement of the North-West Rebellion. Although Louis Riel proved to be victorious at Duck Lake, the general agreement among historians is that the battle was strategically a disappointment to his cause.
