Gordon was not long in the trenches before he came under fire, and the account of his first experience of real warfare may be given in his own words:--
"The night of February 14th I was on duty in the trenches, and if you look at the plan I sent you and the small sketch enclosed I will explain what I had to do. The French that night determined to join their sentries on their right and our sentries on our left, in advance of their and our trenches, so as to prevent the Russians coming up the ravine, and then turning against our flank. They determined to make a lodgment in the ruined house marked _B_ on the sketch, and to run a trench up the hill to the left of this, while I was told to make a communication by rifle-pits from the caves _C_ to the ruined house _B_. I got, after some trouble, eight men with picks and shovels, and asked the captain of the advance trench to give me five double sentries to throw out in advance. It was the first time he had been on duty here; and as for myself, I never had, although I kept that to myself. I led forward the sentries, going at the head of the party, and found the sentries of the advance had not held the caves, which they ought to have done after dark, so there was just a chance of the Russians being in them. I went on, however, and, though I did not like it, explored the caves almost alone. We then left two sentries on the hill above the caves, and went back, to get round and post two sentries below the caves. However, just as soon as we showed ourselves outside the caves and below them, bang! bang! went two rifles, the bullets hitting the ground close to us. The sentries with me retired in a rare state of mind, and my working party bolted, and were stopped with great difficulty. What had really happened was this: It was not a Russian attack, but the two sentries whom I had placed above the caves _had fired at us_, lost their caps, and bolted to the trench. Nothing after this would induce the sentries to go out, so I got the working party to go forward with me. The Russians had, on the report of our shots, sent us a shower of bullets, their picket not being more than 150 yards away. I set the men to work, and then went down to the bottom of the ravine, and found the French in strength hard at work also. Having told them who we were, I returned to the trench, where I met Colonel ---- of the 1st Royals. I warned him if he went out he would be sure to be hit by our own sentries or the Russians. He would go, however, and a moment afterwards was hit in the breast, the ball going through his coats, slightly grazing his ribs, and passing out again without hurting him. I stayed with my working party all night, and got home very tired."
