In 1688, he accompanied William, Prince of Orange, in his expedition to England – the "Glorious Revolution" which deposed James II. The following year, Ginkell distinguished himself by a memorable exploit—the pursuit, defeat and capture of a Scottish regiment that had mutinied for James at Ipswich, and was marching northward across The Fens. It was the alarm excited by this mutiny that facilitated the passing of the first Mutiny Act. In 1690, Ginkell accompanied William III to Ireland to take on the Franco-Irish Jacobites, and commanded a body of Dutch cavalry at the Battle of the Boyne. On the King's return to England, General Ginkell was entrusted with the conduct of the war in Ireland. (See also Williamite war in Ireland).
