Alexander continued his march as far as the river Beas encountering opposition from the local tribes. He wanted to proceed still further eastwards towards the Gangetic valley. But he could not do so because his soldiers refused to fight. Hardships of prolonged warfare made them tired and they wanted to return home. Alexander could not persuade them and therefore decided to return. He made arrangements to look after his conquered territories in India. He divided the whole territory from the Indus to the Beas into three provinces and put them under his governors. His retreat began in October 326 B.C. and the return journey was not free from ordeals. Many republican tribes attacked his army. Anyhow he managed to reach beyond the Indus. On his way he reached Babylon where he fell seriously ill and died in 323 B.C.

Effects of Alexander’s invasion

The immediate effect of Alexander’s invasion was that it encouraged political unification of north India under the Mauryas. The system of small independent states came to an end. Alexander’s invasion had also paved the way for direct contact between India and Greece. The routes opened by him and his naval explorations increased the existing facilities for trade between India and West Asia. However, his aim of annexing the northwestern India to his empire was not fulfilled due his premature death. His authority in the Indus valley was a short-lived one because of the expansion of Mauryan Empire under Chandragupta Maurya.
