as you have seen I've added a bit of movement. It's up to the next posters to decide the size of the band that is attacking us. Any other player can decide to be in sight and join this day skirmish.
As for German tactics, I quote from Tacitus:
"Swords they rarely use, or the larger spear. They carry javelins or, in their own language, framms, pointed with a piece of iron short and narrow, but so sharp and manageable, that with the same weapon they can fight at a distance or hand to hand, just as need requires. Nay, the horsemen also are content with a shield and a javelin. The foot throw likewise weapons missive, each particular is armed with many, and hurls them a mighty space, all naked or only wearing a light cassock.
In arraying their army, they divide the whole into distinct battalions formed sharp in front. To recoil in battle, provided you return again to the attack, passes with them rather for policy than fear."
Good guerrilla tactics
