TO THE INVASION OF INDIA.--_Babylon_ and _Susa_ with all their treasures, and, afterwards, _Persepolis_ and _Pasargadae_, fell into the conqueror's hands. He set fire to Persepolis, and sold its male inhabitants into slavery. He pursued _Darius_ into Media, Hyrcania, and Parthia, where the flying king was murdered by _Bessus_, one of his own nobles, that he might not give himself up to Alexander. He then marched east and south through _Persia_ and the modern _Afghanistan_. He tarried at _Prophthasia_ (Furrah) for two months. Here it was that he charged _Philotas_, one of his best officers, with a conspiracy against his life, and put him to death; and after this he ordered the murder of _Parmenio_, his best general, who had been a companion in arms of King Philip. Founding cities in different places as he advanced, he crossed the _Oxus_, marched through _Sogdiana_, and crossed the _Jaxartes_ (Sir-Daria). While at _Samarcand_, in a drunken revel, he slew _Clitus_, the friend who had saved his life in the battle of the Granicus. In a fit of remorse he went without food or drink for three days. In _Bactra_, the capital of _Bactria_, he married _Roxana_, a princess of the country. By this time his head was turned by his unexampled victories, conquests and power. He began to demand of his followers the cringing adulation that was paid to Oriental monarchs, and when it was denied was ready to inflict summary vengeance. TO THE DEATH OF ALEXANDER.--Crossing the eastern Caucasus (the _Hindu-Kush_), Alexander moved down the right bank of the _Indus_, subduing the tribes whom he met in his path. On the further side of the _Hydaspes_, he met the Indian prince _Porus_, whom he defeated and captured, and converted into an ally. He continued his marches and his line of victories as far as the river _Hyphasis_. Here the Macedonian troops would go no farther. Alexander turned back (327 B.C.), and with his army and fleet moved down the _Hydaspes_ to the _Indus_, and down the _Indus_ to the sea. _Nearchus_, his admiral, sailed along the shore to the west, while Alexander conducted the rest of the army amid infinite hardships through the desert, and finally met him on the coast. In the beginning of the year 325, he reached _Susa_. Here he plainly manifested his purpose of combining Macedonia and Greece with the East in one great empire. He adopted the Persian costume and ceremonial, and married both the daughter of _Darius III_. and the sister of _Artaxerxes III_. He prevailed on eighty of his Macedonian officers and ten thousand Macedonian soldiers to take Persian wives. For himself he exacted the homage paid to a divinity. These measures, looking to the amalgamation of Macedon and Greece with the East on terms of equality, were most offensive to the old comrades and subjects of Alexander. He was obliged to quell a mutiny, which he accomplished with consummate address and courage (July, 324 B.C.). In the marshes about Babylon, a place which he
