Hi Nell,
Sir Thomas ERPINGHAM is widely reported to have been the overall commander of the English archers at Agincourt:-
"He [] fought there with King Henry V, famously at Agincourt where he was in command of the king's deadly archers, giving the signal to fire with the mysterious command recorded by French heralds as "Nestroque!" Historian Matthew Bennet, on a visit to Norfolk, recently recognised this as strong Norfolk dialect (still spoken in some parts) for "Now strike"! Shakespeare makes him an older man at Agincourt with Henry, glad to rest his head on the ground to sleep like a king."http://www.norfolkheraldry.org.uk/Sir_Thomas_Erpingham.htmlAs far as I have read the English battle line consisted of a pretty crude formation of the men-at-arms and cavalry lined up in the centre with a flank of archers on either side. Sir Thomas ERPINGHAM was supposed to have ridden out in front of the lines and given the command to the archers before withdrawing to the middle to fight alongside Henry V.
Obviously each flank of archers probably had their own commanders and were divided into sub-units so perhaps Sir Anthony DOD(D)(E) was leader of one of these? Or were the archers divided into a longbow group and a shortbow group? Alternatively perhaps ERPINGHAM was not in command of the archers really and was just acting as the King's deputy in giving the order to fire and to start the attack on the French, but his role has been twisted by Shakespear etc?
Anthony DODDE does seem to have come from a family with a strong background in archery as do many Cheshire families. His father was called David DOD and there is a record of an archer of that name being in the Kings Bodyguard in the late 1300s, although according to the following the Kings Bodyguard may have ended up fighting against the King and dying at the Battle of Shrewsbury!

Although the fact that Anthony DOD is listed in Visitations as having been knighted at Agincourt, and likely had a background in archery, is there a place where his role would have been recorded in more detail?
