We were talking to the officers of another regiment when they began. Two came in quick succession over the eastern wall of the valley and then one over the western. All three burst--two on impact, one in the air. A fourth ripped along a stone shelter behind which skirmishers were firing. A fifth missed the valley altogether and screeched away into the plain clear of the hills. The officers and men were quite callous. They scarcely troubled to look up. The soldiers went on smoking or playing cards or sleeping as if nothing had happened. Personally I felt no inclination to any of these pursuits, and I thought to sit and wait indefinitely, for the caprice of one of these shrieking iron devils would be most trying to anyone. But apparently you can get accustomed to anything. The regiment where the officer had been killed a few minutes before was less cheerful and callous. The little group of officers crouching in the scanty shelter had seen one of their number plucked out of their midst and slain--uselessly as it seemed. They advised us to take cover, which we would gladly have done had there been any worth speaking of; for at this moment the Boers discharged their Vickers-Maxim gun--the 'pom-pom'--and I have never heard such an extraordinary noise. Seven or eight bangs, a rattle, an amazing cluttering and whistling overhead, then the explosions of the little shells, which scarred the opposite hillside in a long row of puffs of brown dust and blue-white smoke, suggesting a lash from a knotted scourge. 'Look out!' we were told, 'they always follow that with a shell.' And so they did, but it passed overhead without harming anyone. Again the Vickers-Maxim flung its covey of projectiles. Again we crouched for the following shell; but this time it did not come--immediately. I had seen quite enough, however, so we bade our friends good luck--never good-bye on active service--and hurried, slowly, on account of appearances, from this unhealthy valley. As we reached our horses I saw another shell burst among the infantry. After that there was another interval. Further on we met a group of soldiers returning to their regiment One lad of about nineteen was munching a biscuit. His right trouser leg was soaked with blood, I asked whether he was wounded. 'No, sir; it's only blood from an officer's head,' he answered, and went on--eating his biscuit. Such were the fortunes for four days of the two brigades forming Warren's left attack.
