Rinkitink in Oz by L. Frank Baum

All through that terrible night Prince Inga remained hidden in his tree. In the morning he watched the great fleet of boats depart for their own country, carrying his parents and his countrymen with them, as well as everything of value the Island of Pingaree had contained.

Sad, indeed, were the boy's thoughts when the last of the boats had become a mere speck in the distance, but Inga did not dare leave his perch of safety until all of the craft of the invaders had disappeared beyond the horizon. Then he came down, very slowly and carefully, for he was weak from hunger and the long and weary watch, as he had been in the tree for twenty-four hours without food.
