I found this article on a blog about kilts. He makes a great point, that without the Army, the kilt would have been lost to the Scottish.
After the Jacobite rebellion of 1745, the English issued the Act of Proscription. Part of it stated that the punishments for wearing the kilt were:
“imprisonment, without bail, during the space of six months, and no longer; and being convicted for a second offence before a court of justiciary or at the circuits, shall be liable to be transported. . .” No lesser penalties were allowed for. (From Wikipedia.)
The only exception to the ban on the kilt was the Army.
Here’s a great link to military tartans.
I’ve done a fair amount of research on the 93rd Sutherland Highlanders for A Scottish Love. Be careful of this website. The colors will blind you, but they have some great historical paintings and pictures.
