Hi Kevin,

All the illustrations for Agincourt that I think I've seen have tended to show the Cross of St. George.
But then .... where's the 'photographic' evidence (by the contemporary Speedy Scribe)?
Whatever you chose will probably be correct.
On that note, here's a few pages from Osprey MAA on Medieval Heraldry:-



Just chose the livery of the man in charge of the archers at Agincourt (whoever he was).

Cheers,
Andrew
