I had heard that the officers wore square badges as at Waterloo they had formed squares long with the men whilst the other ranks had a triangular backing to the cap badge as they formed "triangles" when there were too few men to support the square. I was also told that other ranks were forbidden from sewing the backing on to the beret for some misdemeanour at some point. However, I have looked through some regimental literature and found nothing to confirm this. Is it just a rumour? Does anyone know the story behind it?
