On regrette de n'être pas blessé comme eux, et de ne pas partager leurs douleurs.

These words were said by the First Consul during the morning of the battle of Marengo, when a cloud of wounded soldiers, aided by some comrades, were passsing him.

I don't get the point of these words.

Literally: "One regrets to be not wounded like them, and not to share their pains."

Why would he want to be wounded and feel pain ?
