The amount was unlimited.

While in the matter of guns, the British Army, which on August 4th, 1914, possessed 486 pieces of different calibres, all told, at the tune of the Armistice was employing 6,437 guns and howitzers of all kinds, including the heaviest monsters of the battle-field.
And with this vast increase in material had gone perpetual advance in organisation.

Artillery commanders were introduced into all armies and corps, with staffs acting under them.

Hence a greater concentration of brain and energy on the special artillery problems--very soon justified by results.

Science and experience had full play, and the continuous artillery battle begun on the Somme ended, as it deserved to end, "in the defeat of the enemy's guns." To that defeat new inventions--or the marvellous development of old ones--were perpetually tending.
