The first casualty when war comes is truth.

The first casualty of war is truth.

The first casualty when war comes is truth (speech, 1917)

Once the war of words begins, truth is the casualty.

It is well known that in war, the first casualty is truth - that during any war truth is forsaken for propaganda.

For the sake of the troops, for the love of the troops, we must not add yet another casualty to this war. We must not let truth be a casualty of this war.
