View from the position of Triangle Point facing north down Caterpillar Valley and the road to Bazentin Le Grand. The children are approaching from the same direction as the German counter attack at 3am on 2nd July 1916.
Triangle Point proved to be the furthest point of advance for the British 4th Army on 1st July 1916. The German counter-attack on the 2nd resulted in the advanced detachment of 17th Battalion Manchester Regiment withdrawing, after running out of their supply of bombs. The German force was subsequently pushed back. For a review of the defenders see https://17thmanchesters.wordpress.com/the-big-push/
