The battlefield itself is very moving, because it is so well preserved. You can go on a relatively simple 1 hour hike around it, and information boards tell you what went on at various stages. It seems more-or-less unchanged since those days. The Scots primarily lost because of the weather and terrain - it had been raining in the area for weeks and on the day there was a rainstorm; the main body of Scottish pikemen got bogged down in knee-high mud in a marshy area which they hadn't realised was there. They lost their order and got pinned down by English longbowmen, and when they finally made their way clear in small exhausted groups they were killed easily by English men-at-arms with billhooks.
Even though that area has been drained now and it hasn't been a particularly wet winter, I had an inkling of what it must have been like - the mud was pretty thick underfoot, by turns slippery and thick. I certainly wouldn't have relished trying to navigate it dressed in armour and carrying a 14 foot pike.
I took some photos and thought I'd share them on the blog as a matter of interest for people interested in medieval conflicts.
