. Luttrell's conduct during the battle became a subject of historical debate. Following the disintegration of the English Army and William's capture of London, Luttrell went to
Ireland. He joined the
Irish Army under the command of
Richard Talbot, Earl of Tyrconnell, which had remained loyal to James and was undergoing a major expansion. Luttrell and other Catholic officers flocked to the army, while Protestants were purged. Protestant inhabitants in Ireland rose, proclaiming their loyalty to William of Orange. While an
uprising at Bandon in
County Cork was quickly put down, a lengthy
Siege of Derry began. Luttrell was given command of a cavalry regiment. He also sat in the
Patriot Parliament called by King James, as a representative for
County Carlow. In 1689 he was made Governor of
Sligo, which had recently been recaptured from the enemy by
Patrick Sarsfield. He immediately set about improving the town's fortifications. Luttrell was a friend and supporter of Sarsfield, and backed his policy of continued resistance following the Jacobite defeat at the
Battle of the Boyne in 1690. His precipitate withdrawal with the cavalry of the left flank at the
Battle of Aughrim gave rise to suspicions of disloyalty. During the
Siege of Limerick, he was found to be in correspondence with the besiegers, and scarcely escaped hanging, bringing his regiment of horse over to the Williamite side after the surrender of the city. As a reward, he received the forfeited estates of his elder brother,
Simon Luttrell, including Luttrellstown, and was made a
major general in the Dutch army. ==Later life==
