Straight to the front by the firing line and supports after repulsing the enemy's attack and demoralizing him with pursuing fire.
Or, by the troops in rear of the firing line when the enemy has reached the defensive position and is in disorder.
[516.] Minor counterattacks are sometimes necessary in order to drive the enemy from important positions gained by him.
DELAYING ACTION.
[517.] When a position is taken merely to delay the enemy and to withdraw before becoming closely engaged, the important considerations are:
The enemy should be forced to deploy early. The field of fire should therefore be good at distances from 500 to 1,200 yards or more; a good field of fire at close range is not necessary.
The ground in rear of the position should favor the withdrawal of the firing line by screening the troops from the enemy's view and fire as soon as the position is vacated.
[518.] A thin firing line using much ammunition will generally answer the purpose. Supports are needed chiefly to protect the flanks.
The reserve should be posted well in rear to assist in the withdrawal of the firing line.
[519.] Artillery is especially valuable to a delaying force.
