From the Department of Irony, via the Guardian: the Battle of Towton has been cancelled due to the poor weather.
“This would have been a rare year when the commemoration coincided with the actual day of the battle, Palm Sunday. In 1461 the two armies fought for ten hours in a blizzard, and this year months of rain and snow have left the site completely waterlogged. The Towton Battlefield Society has sadly announced: "The weather forecast shows no sign of any improvement so we have decided that for safety’s sake we should cancel the event.”
Honestly, the weather gods have laid on a blizzard for them so they got both the day and the weather, you’d think they might be grateful!
