What became of him at last is not certainly known. There are two accounts of his end. One is, that on a certain occasion Alexander got carried too far into the midst of his enemies, on a battle field and that, after fighting desperately for some time, Bucephalus made the most extreme exertions to carry him away. He was severely wounded again and again, and though his strength was nearly gone, he would not stop, but pressed forward till he had carried his master away to a place of safety, and that then he dropped down exhausted, and died. It may be, however, that he did not actually die at this time, but slowly recovered; for some historians relate that he lived to be thirty years old--which is quite an old age for a horse--and that he then died. Alexander caused him to be buried with great ceremony, and built a small city upon the spot in honor of his memory. The name of this city was Bucephalia.
