The English expedition to Portugal also known as the British Brigade in Portugal was a brigade raised during the reign of King Charles II for service in Portugal during the ongoing Portuguese Restoration War against Spain in August 1662. The brigade, many of which were veterans of the English Civil Wars and the Dutch Revolt, then fought in all the major battles and skirmishes under the command of Frederick Schomberg, 1st Duke of Schomberg and remained in Portugal until the end of the war being subsequently disbanded by mid 1668. The brigade under Schomberg's leadership, proved a decisive factor in winning back Portugal's independence.
