Further, there were two smaller (nominally about 500 men, as against 1,000 in the principal units) regiments, both Irish, from the disbanded Royalist Forces which had served with the Spanish Army in Flanders: Fitzgerald's Regiment and Farrell's Regiment. It is not clear which of the earlier Royalist regiments had become Fitzgerald's prior to its appearance in Mardyke in 1661. John Fitzgerald himself became notable during his time in Tangier. Farrell's Regiment had earlier been known as Lord Digby's (or Bristol's): In French service at St Ghislain in Flanders, George Digby had persuaded the regiment to change sides, enabling the town to be recaptured by Spain. Part of the defeated Spanish /Royalist army at the Battle of the Dunes, the remnant the regiment had also made its way to Mardyke under the command of Lisagh (or Lewis) Farrell. The two Irish Royalist regiments, with Harley's English Parliamentarian unit, were shipped more or less directly from Flanders to Tangier and, hence, do not appear on the establishment of the English Army at the time. Completing the first garrison was a troop of horse, nominally the Governor's. In addition, it was agreed to take onto the English establishment a troop of Portuguese cavalry who remained behind.
