The situation was still most critical. The French were sending troops, but with all possible resources utilized we were still gravely outnumbered, and the majority of the men were desperately weary from the Somme battle. On the 11th Sir Douglas Haig issued an Order of the Day, in which he appealed to his men to endure to the last. "There is no other course open to us than 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." Not less solemn was Sir Arthur Currie’s charge to the Canadian Corps before they entered the battle. "Under the orders of your devoted officers in the coming battle you will advance or fall where you stand, facing the enemy. To those who fall I say, ’You will not die, but will step into immortality. Your mothers will not lament your fate, but will be proud to have borne such sons. Your names will be revered for ever and ever by your grateful country, and God will take you unto Himself.’" It is a charge which has the noble eloquence of Cromwell or Lincoln. Within a week it seemed as if the enemy had succeeded. On the evening of 15th April the Germans entered Bailleul, and the next day we withdrew from the ground won in the Third Battle of Ypres to a position a mile east of that town. By the 17th the enemy was in both Meteren and Wytschaete, and this meant that the northern pillar of our defence had gone. The next step for the Germans was to seize Mont Kemmel, the highest ground between them and the Channel, and a position which would presently give them Hazebrouck. The 17th and 18th of April were perhaps the most critical days of the whole battle. The enemy had reached his greatest strength, and the British troops were not yet reinforced at any point within sight of security. On the 17th the Germans had failed in an attack on the Belgians north of Ypres, and next day they failed no less conclusively in a movement on Béthune. This gave us a breathing space, and by the morning of Sunday, the 21st, French troops had taken over the defence of Mont Kemmel, and we had been able to relieve some of the divisions which had suffered most heavily.
