gotcha
I just wanted it clarified in case you knew something I didn't know. We do have treatises and such from the period as far as how the knights moved together in formations of cavalry, from the Knights Templar: "La Régle du Temple." I just wish there was some form of something like this that also pertained to how the Franks fought with sword and shield.
the good news: my Knight instructor in the Adrian Empire has worked rather extensively in both classical texts and "current middle ages" ways. He and I were discussing sword and shield this past week and I plan on discussing it with him again today. He believes the kite shield was used primarily on horseback, or in large war formations where you would have a buddy at your side, whereas the heater when it was invented, was invented for the sole purpose of handling ones opponent "mano y mano." He was telling me that where the kite sits on ones person, the rounded top works very well from horseback, however when on foot, it seems to more or less get in the way.
I'm hoping over the next few weeks we'll be able to create a couple shields and start working with them and see how they move. When I was discussing I:33 with him, he definitely had an evil glint in his eye, which for me, is always a good thing.
