I've started on a project that is turning out to be greater than anticipated. I'm puting together a book of field improvisations made/done by soldiers of our era. A couple of examples include: poking a hole in the ground with a sharpened stick, then pouring molten musket or minnie balls in the hole to make a pencil. Or using the J-hooks from a knap-sack to fasten a gum blanket at the neck for a poncho. Those guys were pretty sharp when it came to improvisation. Any other cool tricks you guys know of that were done back then, and really not represented by reenactors?
