Many volunteers from historic Mississauga served during the Fenian Raids, both leading up to, and in the aftermath of, battles at Ridgeway and Fort Erie in June of 1866. Local militia infantry companies consisting of some 50 men each were formed at Derry West and Grahamsville; Brampton was home to one infantry company and one rifle company; Streetsville formed a half-company of 21 men, and also provided men for a mounted company; volunteers from Port Credit joined with the militia in Oakville and were on service in the Niagara area.
