Battle of Aughrim - The Battle

The Battle

The battle started with Ginkel trying to assault the open flank of the Jacobite position with cavalry and infantry. This attack ground to a halt after determined Jacobite counter-attacks and the Williamites halted and dug in behind stakes driven into the ground to protect against cavalry. The French Huguenot forces committed here found themselves in low ground exposed to Jacobite fire and took a great number of casualties. Contemporaneous accounts speak of the grass being slippery with blood. To this day, this area on the south flank of the battle is known locally as the "Bloody Hollow". In the centre, the Williamite infantry under Hugh Mackay tried a frontal assault on the Jacobite infantry on Kilcommadan Hill. The Williamite troops, mainly English and Scots, had to take each line of trenches, only to find that the Irish had fallen back and were firing at them from the next line. The Williamite infantry attempted three assaults, the first of which penetrated furthest. Eventually, the final Williamite assault was driven back with heavy losses by cavalry and pursued into the bog, where more of them were killed or drowned. In the rout, the pursuing Jacobites manage to spike a battery of Williamite guns.

This left Ginkel with only one option, to try to force a way through the causeway on the Jacobite left. This should have been an impregnable position, with the attackers concentrated into a narrow lane and covered by the defenders of the castle there. However, the Irish troops there were short on ammunition. Mackay directed this fourth assault, consisting mainly of cavalry, in two groups - one along the causeway and one parallel to the south. The Jacobites stalled this attack with heavy fire from the castle, but then found that their reserve ammunition, which was British-made, would not fit into the muzzles of their French-supplied muskets. The Williamites then charged again with a reasonably fresh regiment of Anglo-Dutch cavalry under Henri de Massue. Faced with only weak musket fire, they crossed the causeway and reached Aughrim village with few casualties. A force of Jacobite cavalry under Henry Luttrell had been held in reserve to cover this flank. However, rather than counterattacking at this point, their commander ordered them to withdraw, following a route now known locally as "Luttrell's Pass". Henry Luttrell was alleged to have been in the pay of the Williamites and was assassinated in Dublin after the war. The castle quickly fell and its Jacobite garrison surrendered.

" fire from the castle on the right. . . was insignificant for it slew but a few in the passage. The reason of it was given because the men had French pieces, the bore of which was small and had English ball which was too large."

The Jacobite general Marquis de St Ruth, after the third infantry rush on the Williamite position up to their cannons, appeared to believe that the battle could be won and was heard to shout, "they are running, we will chase them back to the gates of Dublin". However, as he tried to rally his cavalry on the left to counter-attack and drive the Williamite horse back, he was decapitated by a cannon ball. At this point, the Jacobite position collapsed very quickly. Their horsemen, demoralised by the death of their commander, fled the battlefield, leaving the left flank open for the Williamites to funnel more troops into and envelope the Jacobite line. The Jacobites on the right, seeing the situation was hopeless, also began to melt away, although Sarsfield did try to organise a rearguard action. This left the Jacobite infantry on Killcommadan Hill completely exposed and surrounded. They were slaughtered by the Williamite cavalry as they tried to get away, many of them having thrown away their weapons in order to run faster. One eyewitness, George Storey, said that bodies covered the hill and looked from a distance like a flock of sheep.
