Of all the wonderful nights at the front that of July 13th-14th was distinctive for its incomparable suspense. A great experiment was to be tried; at least, so it seemed to the observer, though the staff did not take that attitude. It never does once it has decided upon any daring enterprise. When you send fifty thousand men into a charge that may fail with a loss of half of their number or may brilliantly succeed with a loss of only five per cent., none from the corps commanders and division commanders, who await results after the plans are made, down to the privates must have any thought except that the plan is right and that it will go through. There is no older military maxim than to follow up any hard blow with other blows, in order that the enemy may have no time to recuperate; but in moving against a frontal line under modern conditions the congestion of transport and ammunition which must wait on new roads and the filling in of captured trenches makes a difficult problem in organization. Never had there been and never were there necessary such numbers of men and such quantities of material as on the Somme front. The twelve days succeeding July 1st had seen the taking of minor position after position by local concentrations of troops and artillery fire, while the army as a whole had been preparing for another big attack at the propitious moment when these preliminary gains should justify it. Half a tactical eye could see that the woods of Mametz, Bernafay and Trones must be held in order to allow of elbow room for a mass movement over a broad front. The German realized this and after he had lost Mametz and Bernafay he held all the more desperately to Trones, which, for the time being, was the superlative horror in woods fighting, though we were yet to know that it could be surpassed by Delville and High Woods. In Trones the Germans met attack with counter-attack again and again. The British got through to the east side of the woods, and in reply the Germans sent in a wave forcing the British back to the west, but no farther. Then the British, reinforced again, reached the east side. Showers of leaves and splinters descended from shell-bursts and machine guns were always rattling. The artillery of both sides hammered the approaches of the woods to prevent reinforcements from coming up.
