The Jacobite right was particularly hard hit by a volley from the government regiments at nearly point blank range, but many of its men still reached the government lines and, for the first time, a battle was decided by a direct clash between charging Highlanders and formed infantry equipped with muskets and socket bayonets.
The brunt of the Jacobite impact, led by Lochiel's regiment, was taken by just two government regiments – Barrell's 4th Foot and Dejean's 37th Foot.
Barrell's lost 17 and suffered 108 wounded, out of a total of 373 officers and men.
Dejean's lost 14 and had 68 wounded, with this unit's left wing taking a disproportionately higher number of casualties.
Barrell's regiment temporarily lost one of its two colours.
Major-General Huske, who was in command of the government's second line, quickly organised the counter attack.
Huske ordered forward all of Lord Sempill's Fourth Brigade which had a combined total of 1,078 men (Sempill's 25th Foot, Conway's 59th Foot, and Wolfe's 8th Foot).
Also sent forward to plug the gap was Bligh's 20th Foot, which took up position between Sempill's 25th and Dejean's 37th.
Huske's counter formed a five battalion strong horseshoe-shaped formation which trapped the Jacobite right wing on three sides.

Poor Barrell's regiment were sorely pressed by those desperadoes and outflanked.
One stand of their colours was taken; Collonel Riches hand cutt off in their defence ... We marched up to the enemy, and our left, outflanking them, wheeled in upon them; the whole then gave them 5 or 6 fires with vast execution, while their front had nothing left to oppose us, but their pistolls and broadswords; and fire from their center and rear, (as, by this time, they were 20 or 30 deep) was vastly more fatal to themselves, than us.

With the Jacobite left under Perth failing to advance further, Cumberland ordered two troops of Cobham's 10th Dragoons to ride them down.
The boggy ground, however, impeded the cavalry and they turned to engage the Irish Picquets whom Sullivan and Lord John Drummond had brought up in an attempt to stabilise the deteriorating Jacobite left flank.
Cumberland later wrote: "They came running on in their wild manner, and upon the right where I had place myself, imagining the greatest push would be there, they came down there several times within a hundred yards of our men, firing their pistols and brandishing their swords, but the Royal Scots and Pulteneys hardly took their fire-locks from their shoulders, so that after those faint attempts they made off; and the little squadrons on our right were sent to pursue them".
