Following the failure of the rising of 1715, the Jacobites found new support from Spain, now opposing both Britain and France in the War of the Quadruple Alliance. The Duke of Ormonde led the main invasion fleet from Spain, while an advance party of 300 Spanish soldiers under George Keith, 10th Earl Marischal, arrived in Loch Duich in April 1719, and occupied Eilean Donan Castle. The expected uprising of Highlanders did not occur, and the main Spanish invasion force never arrived. At the beginning of May, the Royal Navy sent ships to the area. Early in the morning on Sunday 10 May 1719 , and anchored off Eilean Donan and sent a boat ashore under a flag of truce to negotiate. When the Spanish soldiers in the castle fired at the boat, it was recalled and all three ships opened fire on the castle for an hour or more. The next day the bombardment continued while a landing party was prepared. In the evening under the cover of an intense cannonade, a detachment went ashore in the ships' boats and captured the castle against little resistance. According to "Worcester"s log, in the castle were "an Irishman, a captain, a Spanish lieutenant, a serjeant, one Scottish rebel and 39 Spanish soldiers, 343 barrels of powder and 52 barrels of musquet shot." The naval force spent the next two days and 27 barrels of gunpowder demolishing the castle. "Flamborough" then took the Spanish prisoners to Edinburgh. The remaining Spanish troops were defeated on 10 June at the Battle of Glen Shiel.
