When, on the evening of the 15th, the enemy again tried to fire the gun tower, they were repulsed without difficulty.

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.
