280 prisoners were taken, and the rest of the defenders fled to the second work.
Two more guns and four mortars were landed and placed in position and, after the stockades had been shelled for a short time, a storming party--under Captain Rose--advanced to the assault.

So heavy a fire was opened upon them that the little column was brought to a standstill, and forced to fall back; with the loss of its commander, and of Captain Cannon of the 89th, while most of the seamen with the storming party were either killed or wounded.
This want of success, against a mere outwork, showed General Cotton that--with the small force at his disposal--it would be worse than useless to renew the attack for, were the outwork carried, the loss would be so great that it would be hopeless to think of attacking Bandoola's main position.

He therefore determined to abstain from further attack, until reinforced.
"Now, Mr.Brooke," he said, as soon as the troops had been taken on board the boats again, "I must bring your services into requisition.

This is just the contingency that we thought might possibly occur.

I cannot advance up the river until Donabew is taken, and I cannot attack the place with the force at my command.
Therefore I will at once write a despatch to General Campbell, for you to carry.
