The War of the Quadruple Alliance began in 1717 in the hopes of defeating Spanish power in Europe post-succession. The alliance of Great Britain, France, the Dutch, and the Holy Roman Empire united to prevent Spain under Philip V from breaking the Treaty of Utrecht (1713). The treaty gave Austria the Spanish Netherlands and parts of Italy while England controlled Gibraltar and parts of the Americas from France. Cardinal Giulio Alberoni, reminiscent of the legendary Richelieu, controlled the Spanish king and convinced him into marriages and the rebuilding of a navy. The Quadruple Alliance began to worry, and rightfully so, as Spain was preparing for war. Most battles were fought throughout Italy in 1718 and 1719, but the Spanish created a plan to invade the British Isles.
Irish exile James Butler, Duke of Ormonde, created the idea to overthrow King George I in favour of James “the Pretender”, son of James II. Catholic Spain supported the invasion and began gathering troops to send over to Ireland. With Spanish troops ready to sail for Britain, Butler dispatched his fleet. Just like the Spanish Armada of 1588, a massive storm destroyed the ships off the coast of Galicia. Just 300 Spaniards managed to arrive in Scotland after being blown off course. George Keith and his Spanish troops landed in County Ross where they managed to get the support of Jacobite highlanders. At Eilean Donan Castle, Jacobites learned of British ships sent to attack them.
HMS Worcester, HMS Enterprise, and HMS Flamborough; the strongest of the ships; arrived near Eilean Donan and sent a parlay ashore to negotiate. When the highlanders opened fire, the British rushed back to their ships and began pounding the castle with shell. British Marines snuck ashore on the night of May 10 and caught the defenders by surpise, forcing their surrender. With a good portion of their support gone, Keith was struggling to keep his operations going. The Spaniards and Jacobites fell back to a mountain pass- Glenn Sheil.
The Spaniards and Jacobites created defenses at Glen Shiel that bisected the road. 200 men of the Galicia Regiment were supported by members of the Clans Mackenzie, MacKinnon, Cameron, McGregor, Murray, and Keith. The entire force numbered about 1,000 men. British forces under the command of Gen. Joseph Wightman arrived on June 10. Montagu’s Regiment and Clayton’s Regiment were sent to defeat the Jacobites along with the Huttel Dutch Regiment, a company of grenadiers, 120 dragoons, and four mortars. The Galicians were positioned on a hill overlooking the enemy while Scottish troops manned the barricades on the road. Murray’s troops were mortared and then charged by the British, cracking after an hour of fighting. George Seaforth attacked the Jacobite left, but he was wounded in the arm by the Galicians in the assault. The flanks began to crumble and the Spanish line caved in, routing uphill away from the deadly fire of the British troops. The Spanish were captured and imprisoned in Edinburgh till the end of the war in early 1720. Keith later became Prussian ambassador to Spain, but the Spanish attacks on Scotland failed spectacularly in a widely overlooked conflict of the early 18th century.
