The film (based on Shakespeare's play) centers around a war between England and France, but almost no actual violence is ever seen
There is a battle at Harfleur, but almost no violence is seen and is never graphic or bloody
After conquering the city, King Henry V threatens to destroy and murder everyone in the city if they do not surrender. The French do surrender, however, and King Henry V insists that none of his soldiers hurt anyone as a result.
A man is sentenced to death by hanging for breaking the law. This is sad and emotional, but little violence is actually seen.
Another final battle at Agincourt where the English defeat the French. Some violence is seen with little blood, but not overly graphic.
The French murder all the English pages, though this mostly takes place off screen. This is disturbing and sad.
After discovering all the dead bodies of the English pages, King Henry V orders all the French prisoners to be executed.
