On April 11th 1918, with the German Spring Offensive well underway, General Douglas Haig sent the following communication to all ranks of the British army:
From: Commander-in-Chief, British Armies in France
To: All ranks of the British Army in France and Flanders
Three weeks ago today the enemy began his terrific attacks against us on a 50-mile front. His objects are to separate us from the French, to take the Channel Ports and destroy the British Army. In spite of throwing already 106 Divisions into the battle and enduring the most reckless sacrifice of human life, he has as yet made little progress towards his goals.
We owe this to the determined fighting and self-sacrifice of our troops. Words fail me to express the admiration which I feel for the splendid resistance offered by all ranks of our Army under the most trying circumstances.
Many amongst us now are tired. To those I would say that Victory will belong to the side which holds out the longest. The French Army is moving rapidly and in great force to our support.
There is no other course open to us but to fight it out. Every position must be held to the last man: there must be no retirement. With our backs to the wall and believing in the justice of our cause each one of us must fight on to the end. The safety of our homes and the freedom of mankind alike depend upon the conduct of each one of us at this critical moment.
Field Marshal Douglas Haig
