The Capture of Trônes Wood (8–14 July) was a tactical incident in the First World War, fought by the British Fourth Army and the German 2nd Army, during the Battle of the Somme. Trônes Wood lay on the northern slope of Montauban ridge, between Bernafay Wood and Guillemont. The wood dominated the southern approach to Longueval and Trônes Alley, a German communication trench between Bernafay Wood and the northern tip of Trônes Wood to Guillemont. A light railway ran through the centre, which was in a dip formed by the east end of Caterpillar Valley sloping away to the west. The wood was pear-shaped, with a base about 400 yd (370 m) wide on Montauban ridge, the rest of the wood running north for about 1,400 yd (1,300 m), coming to a point on a rise towards Longueval village.
