For those who were there the game was Pfeddersheim 1460 (of which I knew nothing before I arrived) but put simply it was a battle between two German armies both with war-wagons. It was put on by Bob from the L&L with an impressive array of 28mm kit.

The enemy deployed in wagonburg blocking my force from....
...the relief of Pfeddersheim
It all got very messy and the wagons are not the most mobile bits of kit.
