On their side the garrison on the terrace disregarded the musketry fire , but , crowded behind the sandbags , kept up a steady and concentrated fire at the flashes of the cannon ; while from the battery below , the gunners , unable to touch the enemy 's battery , discharged grape at the houses tenanted by the enemy 's infantry . The Sepoys , carefully instructed in our service , had constructed shields of rope to each gun to protect the gunners , but those at the best could cover but one or two men , and the fire from the parapet inflicted such heavy losses upon the gunners that after a time their fire dropped , and an hour from the commencement of the cannonade all was still again on both sides . The Sepoy guns were silenced . It was now ten o'clock , and the Warreners went and lay down quietly for a couple of hours . Then they heard the guard changed , and after waiting a quarter of an hour they went out to the battery , having first filled their sponges with water . There they joined Mr. Johnson . `` Ca n't sleep , boys ? ''
