Believing that a war with the United States was inevitable, Canada’s first Prime Minister proposed a plan to amass an army of Sikhs, well-known for their courage in battle, to invade California on behalf of Canada. His strategy was to send these Sikh warriors to California to take control of San Francisco, using it as a safeguard for Montreal and Canada. This perceived threat of a U.S. invasion in 1867 was predicated on a proposed bill from 1866 – which ultimately did not pass – that would have allowed the British colonies to become part of the USA if they wished. This idea wasn’t completely off the table, as there were still discussions about Newfoundland potentially joining the United States instead of Canada up until the late 1940s.
