Krateros he again despatched with the army [through the country of the Arachôtians and Drangians]; while he sailed down himself to the realm of Mousikanos,[176] which was reported to be the most opulent in India, because that sovereign had neither come to surrender himself and his country, nor sent envoys to seek his friendship. He had not even sent presents to show the respect due to a mighty king, nor had he asked any favour from Alexander. He therefore made the voyage down the river so rapidly that he reached the frontiers of the country of Mousikanos before that prince had even heard that Alexander had started to attack him. Mousikanos, dismayed by his sudden arrival, hastened to meet him, taking the choicest presents India could offer and all his elephants with him. He offered to surrender both his nation and himself, and acknowledged his error, which was the most effective way with Alexander to obtain from him whatever one wanted. Alexander therefore granted Mousikanos a full pardon on account of his submission and penitence, expressed much admiration of his capital and his realm, and confirmed him in his sovereignty. Krateros was then ordered to fortify the citadel which protected the capital, and this work was executed while Alexander was still on the spot. A garrison was placed in the fortress, which he thought suitable for keeping the surrounding tribes in subjection. _Chapter XVI.—Campaign against Oxykanos and Sambos_ Then he took the archers and the Agrianians and the cavalry which was sailing with him, and marched against the governor of a district in that part of the country whose name was Oxykanos, because he neither came himself nor sent envoys to offer the surrender of himself and his country.[177] At the first assault he took by storm the two largest cities under the rule of Oxykanos, in the second of which that chief himself was taken prisoner. The booty he gave to the army, but the elephants he led away and reserved for himself. The other cities in the same country surrendered without attempting resistance wherever he advanced; so much were the minds of all the Indians paralysed with abject terror by Alexander and the success of his arms.
