Write in detail how Tawala died?

From the text:

“Never, my lords,” he said, “shall mine old eyes see the like of ye again. Ah! The way that Incubu cut his men down in the battle! Ah! For the sight of that stroke with which he swept off my brother Twala’s head! It was beautiful- beautiful!

Good-bye, old boy; I can’t say any more, but I know that you will come, if it is only to oblige your sincere friend, Henry Curtis P.S.- The tusks of the great bull that killed poor Khiva have now been put up in the hall here, over the pair of buffalo-horns you gave me, and look magnificent; and the ax with which I chopped off Twala’s head is stuck up over my writing-table. I wish we could have managed to bring away the coats of chain armor.

Once more Twala came on, and as he came our great Englishman gathered himself together, and, swinging the heavy ax round his head, hit at him with all his force. There was a shriek of excitement from a thousand throats, and, behold! Twala’s head seemed to spring from his shoulders, and then fell and came rolling and bounding along the ground towards Ignosi, stopping just at his feet.
