Not one of them but was aware that the plight of the two sentries they had left behind them in the fort might at any moment be discovered. The hourly call must be nearly due. When no response came from the sentry whose beat ended at their shed the alarm would at once be given, and in a few seconds the silent form of the sentinel on the bastion would be found, and the whole garrison would be sped to their pursuit. But at this moment of suspense only the Babu was agitated. His natural timidity, and the tincture of European ways of thought he had gained during his service in Calcutta, rendered him less subject than his Mohammedan companions to the fatalism which rules the Oriental mind. To the Mohammedan what must be must be. Allah has appointed to every man his lot; man is but as a cork on the stream of fate. Not even when a low, half-strangled cry came to them across the water, out of the blackness that brooded upon the harbour, did any of the four give sign of excitement. The Babu started, and rose to his feet shivering; the others still squatted, mute and motionless as statues of ebony, neither by gesture nor murmur betraying their consciousness that at any moment, by tocsin from the fort, a thousand fierce and relentless warriors might be launched like sleuth-hounds upon their track. Meanwhile, what of Desmond and the Gujarati? During the months Desmond had spent in Gheria he had made himself familiar, as far as his opportunities allowed, with the construction of the harbour and the manner of mooring the vessels there. He knew that the gallivats of the Pirate’s fleet, lashed together, lay about eighty yards from the head of the jetty under the shelter of the fortress rock, which protected them from the worst fury of the south-west monsoon. The grabs lay on the other side of the jetty, some hundred and twenty yards towards the river--except three vessels which were held constantly ready for sea somewhat nearer the harbour mouth. He had learnt, moreover, by cautious and apparently casual inquiries, that the gallivats were under a guard of ten men, the grabs of twenty. These men were only relieved at intervals of three days; they slept on board when the vessels were in harbour and the crews dispersed ashore. In thinking over the difficult problem of escape, Desmond had found himself in a state of perplexity somewhat similar to that of the man who had to convey a fox and a goose and a bag of corn across a river in a boat that would take but one at a time. He could not, with his small party, man a gallivat, which required fifty oarsmen to propel it at speed; while if he seized one of the lighter grabs, he would have no chance whatever of outrunning the gallivats that would be immediately launched in pursuit. It was this problem that had occupied him the whole day during which Diggle had fondly imagined he was meditating on Angria’s offer of freedom.
