HAD not been in Tahiti long before I met Captain Nichols. He came in one morning when I was having breakfast on the terrace of the hotel and introduced himself. He had heard that I was interested in Charles Strickland, and announced that he was come to have a talk about him. They are as fond of gossip in Tahiti as in an English village, and one or two enquiries I had made for pictures by Strickland had been quickly spread. I asked the stranger if he had breakfasted.

这一句and announced that he was come to have a talk about him.中的 was come 怎么理解？
