FIRING A 12-INCH LONG-RANGE GUN.
The Part Played by each Arm in the Different Phases of the Attack
In modern, well-ordered battle, it is the material strength which counts most. The cannon must crush the enemy's machine-guns. Superiority of artillery is an essential element of success.
According to the latest formula, "the artillery conquers, the infantry occupies."
At each stage of the battle, each arm has a definite role to play.
The Artillery
Before the battle, the artillery must destroy the enemy's wire entanglements, trenches, shelters, blockhouses, observation-posts, etc.; locate and engage his guns; hamper and disperse his working parties.
During the battle, it must crush enemy resistance, provide the attacking infantry with a protecting screen of fire, by means of creeping barrages, and cut off the defenders from supplies and reinforcements by isolating barrages.
After the battle, it must protect the attacking troops who have reached their objectives, from enemy counter-attacks, by barrage fire.
