I'm curious and I need help.

I remembered today this scene from a Shakespeare play, but I can't remember what play it's from and it's driving me crazy. In this scene, a soldier (he has no name and is a minor character) realizes that the battle is lost and his army is defeated. So he grabs his weapon and runs at the enemy. He's defeated instantly and left for dead, but he claims that he can at least say "I fought".

Does anyone know what play this is from? Please and thank you!
