I thought this idea may come in handy for you troops , i remember reading in an archaeolgy (sp?) book that the scots at this time used a unique system for reinforcing their castles . wat they would do i cant remmeber if it was mixed in with the mortar type stuff or entirely on its own , anyways wat they would do is put sand in the cracks between the stones and then heat the whole wall so that the sand would melt and form into glass just thought it was quite a cool thing i could share wth you troops .
