Battle of Bannockburn 1314
As luck would have it I (the Englishman) was posted to the Scottish Army with my daughter. My Scottish wife and mother-in-law along with my two sons were playing the English. A tad ironic ;) as I stood in line next to no other than Robert the Bruce, played by a nine year old little (Scottish) girl (see below):
Suffice it to say that I had a whale of a time, though I must confess to mixed emotions as on Day 2 of the battle my unit of Scottish bow felled the English king (Edward II) and won the game. However as I left the Battle Room I felt elated, pondering but one question 15mm or 25/28mm?
