In 1678, Monmouth was the commander of the Anglo-Dutch brigade, now fighting for the United Provinces against the French, and he distinguished himself at the Battle of Saint-Denis in August that year during the Franco-Dutch War, further increasing his reputation. The following year, after his return to Britain, he commanded the small army raised to put down the rebellion of the Scottish Covenanters and despite being heavily outnumbered, he decisively defeated the (admittedly poorly equipped) Covenanter rebels at the Battle of Bothwell Bridge on 22 June 1679.
