Punjab, Land of Five Rivers

One close look at the map will make you realize that Punjab is an enormous alluvial plain that counts far more than the five main rivers. Situated at the foot of the Himalayas, it covers a surface of over 50,000 square kilometers. Its watershed is fed by snow and glacial meltwater from the world’s highest peaks, like the Karakorum, the Hindu Kush, and the Himalayan Mountains.

The Achaemenids had only conquered the lands west of the Indus, meaning that once Alexander crossed this mighty river, he entered uncharted territory. Modern historians do not spend much time following the king’s march further east and his countless river crossings but instead focus on battlefields, sieges, and other ruthless fights. However, each and every crossing, including the numerous tributaries, is an enormous logistic enterprise. It makes you wonder how many of these rivers, streams, and waterways the Macedonians had to cross by any means available. That alone is a gigantic task!

After taking the Aornos Rock, Alexander headed for the Indus River, where Hephaistion had worked hard to build a pontoon bridge across the river as well as a fleet partly new and partly reassembling the elements which had been carried along. The crossing of the Indus took place at Ohind, modern Hund, in north-western Pakistan (see: Alexander crossing the Indus at Ohind).

Once his troops reached the opposite bank, Alexander headed for the capital Taxila at the junction of the major trade routes from Bactria, Kashmir, and the Ganges valley. This was the realm of Omphis, the son of King Taxiles, who had visited Alexander while he was still in Bactria and died before he arrived in India. Besides sending provisions to Hephaistion during the construction works, King Omphis welcomed Alexander with 200 silver talents, 3,000 oxen, 10,000 sheep, 30 elephants, and 700 Indian cavalry and 5.000 infantry.

The next river Alexander had to tackle was the Hydaspes (modern Jhelum), where the famous battle against King Porus took place (see: The Battle of the Hydaspes and the genius of Alexander), a masterpiece and a genius enterprise that was never surpassed.

As casually mentioned by Arrian, Alexander marched on through the populous region, taking some thirty-seven towns and many villages as the natives surrendered without much protest. Their lands were graciously handed over to King Porus.

The next obstacle was the Acesines River (modern Chenab) which was so broad and swift that Ptolemy found it necessary to mention it in his biography used by Arrian. It is hard to simply imagine a three kilometers wide river and how much one could see of the opposite bank. The Macedonians used boats to get across, but navigation among the rocks was a true challenge, and many were broken up, and the men were swept away by the current. The floats for the baggage and horses fared much better as they were far more shallow than the boats, but the trip was nevertheless one more logistic challenge.

The Hydraotes River (modern Ravi) was another major river on Alexander’s path, and as he marched through these lands, most Indian tribes surrendered without resistance. Those who refused were, of course, taken by force. Sangala was such an exception (see: The siege of Sangala). The tribes nearby the city had sought and found refuge inside its strong walls. Eventually, Sangala was taken by an assault in which up to 17,000 Indians were killed while over 70,000 were taken prisoner.

The last of the five major rivers was the Hyphasis River (modern Beas). Here, the Macedonians bluntly refused to follow Alexander anywhere closer to the edge of the world despite his eloquent and fiery speech. This was a severe blow to the king’s ego and pride, but he issued the order to retreat after three days.

Obviously, Alexander withdrew in style, and after building twelve altars (see: Alexander erected twelve altars on the banks of the Hyphasis) to thank the gods for having led him so far as conqueror and leaving an impressive memorial to his own accomplishments, he turned around having to cross the Hyphasis, Hydraotes, and Acesines once again. He sailed down the Hydaspes to ultimately reach the Indus River.

Some scholars consider Alexander’s experience in Punjab as useless and a waste of time, but it is hard to believe that he would do anything without reason. He would not endanger the life of his Macedonians lightly, and he certainly would not have invested nine months of this life on a sole whim. Judging Alexander’s conduct with today’s eyes is impossible. Besides, we only have sparse historical documentation to support his decision-making.
