Agincourt, fought on October 25th 1415, on St Crispin's Day, is one of the best known battles, in part through the brilliant depiction of it in Shakespeare's Henry V, in part because it was a brilliant and unexpected English victory and in part because it was the first battle won by the use of the longbow. This was a weapon developed in this form only by the English - parishes were forced to train boys from as young as eight daily - and enabled them to dominate the European battlefields for the rest of the century.
