He also served as Governor of Scilly Isles (1647) and Governor of Barbados (1650–1652).

In 1646 he received a naval command, In August 1647 he was appointed Governor of Scilly Isles a post he held until January 1647.

In 1649, he was appointed Admiral of the Irish Seas. In 1650 Ayscue was appointed Governor of Barbados and Commander of the squadron sent to the island. In 1651, he served with General at Sea Robert Blake in the capture of the Scilly Isles from Sir John Granville, 1st Earl of Bath. Later that year he captured Barbados from Lord Willoughby and the other English colonies in the Americas. In the First Anglo-Dutch War he was defeated by the Dutch Commodore Michiel de Ruyter at the Battle of Plymouth.

He was held prisoner during the war in the Dutch state prison of Loevestein, and almost certainly never again took to sea as admiral. In December 1671, he was the President of the Court Martial of Rear-Admiral Sir William Jennings, held on board .
