[1] In 1687, Luttrell was appointed Lord Lieutenant of County Dublin and made a member of the Privy Council of Ireland by the Earl of Tyrconnell.
In this capacity, he raised a regiment of 374 dragoons, prepared Dublin's defences against an awaited assault, and worked with Terence MacDermott to disarm the city's Protestant inhabitants.
[2] Following the lifting of the first Siege of Limerick in 1690, Luttrell was a member of the delegation which travelled to the Jacobite court at Château de Saint-Germain-en-Laye to call for the removal of Tyrconnell from the viceroyalty.
He returned to Ireland on 28 October 1691, shortly after the Jacobite defeat, but Luttrell refused to avail himself of the pardon granted to him under the Articles of Limerick and left again for France.
He served under Nicolas Catinat in Italy and Louis Joseph, Duke of Vendôme in Catalonia during the Nine Years' War.
