The Capture of Trônes Wood (8–14 July) was an action 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.
