Grenzers!

 I’ve always liked grenzers. I read Rothenberg’s “ Military border in Croatia “ from the Uni library as a student  and that increased my interest. They have cool uniforms, a bit of dash about them and interesting weapons  such as double barrelled muskets rifles and spear musket rests! What’s not to like?  So it is not surprising that I raised a unit for the 1790 vanity project, here are three stout fellows-

Who can resist the read cloaks , cool hats and muskett rest spears?

I have been wondering how much use the spiky rest would be in combat? Might deter cavalry perhaps but could be a liability ? I always imagine they threw them away  or “ forgot” to take them with them. Anyone tell me more or even supply me with a period quote about the use of spike musket rests in combat?
