Another account relates that the enemy occupied the positions on the Aisne that they had taken up in 1870, and their guns were all placed in concrete positions, carefully prepared against the event. After the Camerons took up their position, the distance between the opposing forces was about a thousand yards, with fairly open ground between, and the regiment was ordered to attack the trenches held by the enemy. The whole brigade advanced under heavy shell fire until within 250 yards of the enemy's position--and then the man who tells of this incident was struck down by shell fire and rendered unconscious, so that he did not see the result of the advance. He knew, however, that it must have been successful, since he was still behind the British line when he recovered consciousness. It was later on, when the battle of the Aisne had taken on the nature of a siege action, that the cave disaster occurred which caused the deaths of over thirty officers and men of the regiment. Near the firing line was a large, spacious cave, which was used partly as a collecting base for the wounded, and partly as the regimental headquarters; and on the 25th of September, while the German artillery was shelling the British positions, the roof of the cave was struck by one of the big German shells, with the result that it fell in, burying thirty-five officers and men. The cave was some 300 yards behind the firing line, so that the incident went unobserved for some time--though it is doubtful if anything could have been done even had prompt action been taken, since the fall of rock and earth was so heavy that most of the men in the cave must have been killed instantaneously. Four of the occupants, however, were able to shout for help, being pinned down by masses of rock at the back of the cave when the roof fell in; and, nearly two hours after the accident, other men of the regiment heard the shouts of those imprisoned, and set to the work of rescue. Three men had been liberated, and while the rescuers were at work getting out the fourth man another shell landed in the same spot, covered in the pinned man, and blew his would-be rescuer to pieces. But this wounded man, though buried anew, was still alive, though he lost consciousness after two hours. An officer and three men of the Scots Guards finally dug him out, after he had been buried for about six hours, and he was sent away to hospital and recovery.
