Presumably Albert is large enough to have a sizeable number of disaffected youngsters who have nothing better to do in the evenings. They expressed their opinions in the visitors' book, briefly and in very basic language - but only, presumably, after their teachers had signed, mentioning the name and address of the school. They came from the same town as the men who had died there. I am the Head Teacher of a school myself, and thought I might write to the pupils who had so offended me and other subsequent visitors, judging by their later comments. But I decided against it.
Young people are often outspoken.
I also had a nagging doubt. To the South of the Battle area, this village was one of the success stories of 1st July, 1916. It was captured in the afternoon. Martin had gone home on leave shortly before the battle and had passed the time referring to maps and building himself a clay model of the area over which he and his men were to attack on the morning of 1st July. He formed the opinion that when they left their trench and scrambled down a slope soon afterwards, they would come under fire from a machine-gun known to be situated in the civilian cemetery of Mametz, just a few hundred yards away to the right of their line of attack, if the gun and its crew had survived the bombardment.
