Actually there were 2 Scottish Confederate units. The Charleston Highland Guards who modeled their dress uniforms after the British Black Watch of the period with black watch kilts, red short coats and blue diced bonnets and the Union Light Infantry who wore black watch trews and blue frock coats and bear fur caps. They were NOT named the Union light infantry in honor of the union of Scotland and Ireland, they were from Union County S. Carolina.

Neither unit EVER wore these uniforms in combat and both were militia units that were absorbed into larger units early in the war forming companies of the 1st later the 14th South Carolina Infantry.
