Suddenly an infernal racket broke out over to our left. First there came a few scattered cracks of rifle fire. Then I could hear clip firing and the rattle of machine guns. I learned later that the Scots Greys and the 12th Lancers had come across about seven thousand Germans resting in a wide gully. The Greys and the Lancers, catching them unawares by cutting down their sentries who had no opportunity even to give the alarm--charged through them, then back again. Three times they repeated their performance, while some of our brigade got on to the flanks and poured in such a rapid fire that the Prussians had no opportunity to re-form to meet each repetition of the attack. The details do not matter, but they made up for the annihilation of the Munster Fusiliers. In the newspaper accounts of the campaign this incident was described as the "Great St. Quentin Charge," in which, it was asserted, the Black Watch (foot soldiers) participated, holding onto the stirrups of the Scots Greys. This bit of colouring was an inaccuracy. We aided the Greys and the Lancers with rifle and machine-gun fire only. When the firing ceased and the Greys and the Lancers came cantering past, we learned from them the details of the Battle of "St. Quentin." At nightfall our section was still guarding the road at a point from which a cart road branched off at right angles to the main thoroughfare. It was here that the outpost received instructions in a few French phrases, the main one being "_Votre passe, s'il vous plait_." ("Your pass, please.") This was because the road was open to refugees who were fleeing from the Boches, and who had to show passes before being allowed to go on. The absence of the pass meant that the person would be sent to headquarters for examination. It was quite natural that some of us Scots should find it difficult to make ourselves familiar with these phrases. However, we were all willing to try. One strapping Highlander, weary and footsore but daunted by nothing, practised the phrases dutifully, though the French words were almost lost in the encounter with his native Scotch. We chuckled, but he merely glowered at us indignantly, and then went to take his place on sentry go. Two Frenchmen came along in a wagon. The Highlander blocked their way and sternly uttered what he conceived to be the phrase he had been told to use. The Frenchmen sat mystified. There was a roar of laughter when the Highlander, losing patience, shouted: "Pass us if ye daur!" Then his sergeant came to the rescue.
