The Glasgow Highlanders. The Photo Identification feature attracts more reader queries than anything else on this site. Folk are always sending in photos of their ancestors in the hope that I can help work out which unit they served with. In a surprising number of cases, the answer turns out to the Glasgow Highlanders. Though sometimes, I’ve come close to giving the wrong answer. The Glasgow Highlanders were part of the Highland Light Infantry, in the First World War, they were the HLI’s 9th Battalion, but their uniform was modelled on the Black Watch. I was about to get back to someone to say the photo they had sent in was entirely consistent with a Company Sergeant Major in the Black Watch when I looked a second photo. It showed not the CSM, but his best friend, who was killed in action. The friend was wearing what looked like a Black Watch kilt and a Tam o’ Shanter. It was the headgear that gave the game away. The Black Watch wore red hackles in their Tam o’Shanters. This guy had a badge and the Glasgow Highlanders wore a badge. My hunch that the CSM was a Glasgow Highlander panned out. It was even possible, because he won the Military Medal, to come up with his army number. A Second World War photo showed what looked like a Black Watch kiltie with the lion rampant shoulder flash of 15th Scottish Division on his upper sleeve. The thing is that the Black Watch did not have a battalion serving with the Division. But one of the two Glasgow Highlander battalions in the war was part of the division. The guy in the photo proved to be one of the large number of Englishmen who served in kilted regiments in both World Wars. So, anyway, if the First World War photo shows suggests the Black Watch but the soldier has a badge rather than a hackle on his Tam o'Shanter, then possibly he's a Glasgow Highlander. Oddly, I've never had a query that involved the Royal Scots' "Dandy" Ninth Battalion, which also wore kilts during the First World War.
