King Henry V of England kneels in the background, crown on ground, on the field of Agincourt where had just been fought an epic battle between English & French. The kneeling priest in the foreground leads the soldiers in prayers of thanksgiving for their victory, which God had granted them. The priest and crossbearer are the only figures with their mouths open, thus indicating the intonation of one of the hymns that King Henry commanded to be sung in thanksgiving and charity:
"Do we all holy rites;
Let there be sung 'Non Nobis' and 'Te Deum;'
The dead with charity enclosed in clay."
From Shakespeare's Henry V
