Hubbo set off, and when he reached his own vessel he sent a boat with a message to each of the ships in turn. Meanwhile, thinking the appearance of a petala alongside of the subahdar’s sloop might awaken suspicion or at least curiosity in the fort, Desmond decided to send it down the river in charge of Hossain. He was thus left alone on deck with the subahdar’s third man. For a time the man, standing far forward, was unaware of the striking change in the personality garbed in the subahdar’s clothes. But glancing back at length, he started, looked a second time, and after a moment’s hesitation walked down the deck. "Go back to your post," said Desmond sternly, "and see that you keep a good look-out for the Firangi’s ships." The man salaamed and returned to the prow in manifest bewilderment. More than once he looked back as he heard strange knockings from below. Desmond only smiled. If the sound was heard from the forts, it would be regarded merely as a sign that the preparations for sinking the vessel were not yet completed. Time passed on, and ever and anon Desmond looked eagerly down the river for a sign of the oncoming fleet. At last, somewhere about midday, he observed signs of excitement in Tanna Fort, and almost simultaneously saw a puff of smoke and heard a report from one of its guns. Shortly afterwards he observed the spars of a British-built ship slowly approaching up-stream. In full confidence that the scheme for blocking the river was now frustrated, he awaited with patience the arrival of the fleet, wondering whether the forts would make a determined resistance. Slowly the vessel drew nearer. Another shot was fired from the fort, with what result Desmond could not tell. But immediately afterwards he heard the distant report of a heavy gun, followed by a crash near at hand, and a babel of yells. A shot from the British ship had plumped right in the centre of Tanna Fort. At the same moment Desmond recognized the figure-head. "’Tis the _Tyger_!" he said to himself with a smile. "Won’t Captain Latham grin when he sees me in this rig!" Then he laughed aloud, for the valiant defenders of Tanna Fort had not waited for a second shot. They were swarming helter-skelter out of harm’s way, rushing at the top of their speed up the river and leaving their fortress to its fate. On the other bank the garrison of Aligarh Fort had also taken flight, and were streaming along with excited cries in the direction of Calcutta. The man in the bows of the sloop looked amazedly at the new subahdar. Why did he laugh? Why did he not wave the green flag that lay at his hand? When were the men who had gone below going to knock out the stoppings of the holes and take to the boat with himself and their commander? But the subahdar still stood laughing.
