He was captured and condemned to death.

Now there was an opportunity for Anne's nature to assert itself, and it did, but it was a very different sort of nature from that of Mary Reed.

Just before his execution Anne was admitted to see her husband, but instead of offering to do anything that might comfort him or palliate his dreadful misfortune, she simply stood and contemptuously glared at him.

She was sorry, she said, to see him in such a predicament, but she told him plainly that if he had had the courage to fight like a man, he would not then be waiting to be hung like a dog, and with that she walked away and left him.
On the occasion when Captain Rackham had been captured, Mary Reed and her husband were on board his ship, and there was, perhaps, some reason for Anne's denunciation of the cowardice of Captain Rackham.

As has been said, the two women were good friends and great fighters, and when they found the vessel engaged in a fight with a man-of-war, they stood together upon the deck and boldly fought, although the rest of the crew, and even the captain himself, were so discouraged by the heavy fire which was brought to bear on them, that they had retreated to the hold.
Mary and Anne were so disgusted at this exhibition of cowardice, that they rushed to the hatchways and shouted to their dastardly companions to come up and help defend the ship, and when their entreaties were disregarded they were so enraged that they fired down into the hold, killing one of the frightened pirates and wounding several others.
