The Brigade, in the service of the Dutch Republic, was then stationed at Bergen op Zoom and later moved to Maastricht. He had reached the rank of Captain when like other officers he left the Dutch service in 1782 during the Fourth Anglo-Dutch War and was on half-pay until 29 September 1787, when he joined the 60th Foot (Royal American Regiment), but the regiment was reduced and he was briefly on half-pay again before joining the 13th Light Dragoons on 30 June 1788. In February 1793, shortly after the French Revolutionary War had begun, Hope served as aide-de-camp to Sir William Erskine in the Flanders Campaign. On 25 March 1795, a few days after Erskine's death, Hope was promoted to major in the 28th Light Dragoons, becoming lieutenant-colonel of that regiment on 20 February 1796. Sent to the Cape Colony, the 28th, under Hope's command, helped to rebuff a Dutch attempt in August, to reclaim the colony.
