Not much is recorded about the regiment's history before Culloden. It may have been on the march to Derby, John Gordon himself and the regimental priest certainly were. The first recorded action of the regiment is on the 11th of February 1746, when John Gordon and his regiment, used a couple of guns to persuade lieutenant Molly to surrender Ruthven barracks in return for a safe passage to Perth. Glenbucket then proceeded to burn the barracks. Glenbucket's were not present at the siege of Sterling, or the battle of Falkirk. At this time they were in the north of Scotland, operating against the government's independent highland units.
At the battle of Culloden, Glenbucket's had rejoined the main jacobite army. Originally they stood in the second line at Culloden, but after Lord George Murray ordered the front line of highland regiments to close up to the right, Perth's and Glenbucket's were moved up to the first line to fill the gap which had been created on the left flank. When the Jacobite army advanced both Perth's and Glenbucket's advanced with them, but due to swampy ground and small ponds to their front they were unable to make contact with the enemy. So for most of the battle they engaged in a firefight with the government troops opposite them. Glenbucket's and Perth's suffered relatively few casualties during the battle. When the government dragoons launched their attack, Glenbucket's and Perth's on the left flank were able to hold them off for a short time, presumably helped by the same swampy ground which had stopped their own advance. The dragoons soon by passed the two regiments in search of easier targets. When the general retreat and disintegration of the Jacobite army began, both regiments were able to retire from the field virtually intact and in good order.
Along with the remnants of John Roy Stewart's regiment Glenbucket's and Perth's, escorted Prince Charles from the field for at least part of the way.
There is no record of what happened to Glenbucket's regiment after Culloden, it may have been amongst the units which gathered at Ruthven barracks after the battle, Perth's regiment was there. Whatever happened the regiment was disbanded soon after Culloden, never to be heard of again, (or will it !?).
