The Spanish colors were flying from his topmast, and he hoped to be able, without being suspected of any evil designs, to get so near to the man-of-war that he might run alongside and boldly board her.
But something now happened which Pierre could not have expected.

When the commander of the war-vessel perceived that one of the fleet under his charge was leaving her companions and putting out to sea, he could imagine no reason for such extraordinary conduct, except that she was taking advantage of the fact that the wind had not yet reached his vessel, and was trying to run away with the pearls she had on board.
From these ready suspicions we may imagine that, at that time, the robbers who robbed robbers were not all buccaneers.
Soon after the Spanish captain perceived that one of his fleet was making his way out of the river, the wind reached his vessel, and he immediately set all sail and started in pursuit of the rascals, whom he supposed to be his dishonest countrymen.
The breeze freshened rapidly, and when Pierre and his men saw that the man-of-war was coming toward them at a good rate of speed, showing plainly that she had suspicions of them, they gave up all hope of running alongside of her and boarding her, and concluded that the best thing they could do would be to give up their plan of capturing the pearl-fishing fleet, and get away with the ship they had taken, and whatever it had on board.

So they set all sail, and there was a fine sea-chase.
The now frightened buccaneers were too anxious to get away.

They not only put on all the sail which the vessel could carry, but they put on more.

The wind blew harder, and suddenly down came the mainmast with a crash.
