midnight
On the following night a determined attack in force was made , on all sides of the fort ; but was defeated with much loss . The enemy now began to make a great noise , with drums and pipes , in the summer house . This lasted continuously for several days , and one of the natives , who was aware that the enemy had started tunnelling , guessed that this stir might possibly be made to drown the noise of the mining . Men were put on to listen and , at midnight , the sentry in the gun tower reported that he heard the noise and , next morning , the sound was distinctly audible within a few feet of the tower . It was evident that there was no time to be lost and , at four o'clock in the afternoon , Lieutenant Harley and a hundred men issued from the fort , at the garden gate , and rushed at the summer house . It was held by forty of the enemy , who fired a volley , and fled after some sharp hand-to-hand fighting . The head of the mine was found to be in the summer house , and the tunnel was full of Chitralis .
