Alexander the Great fought a series of battles from his adulthood until his death, increasing his empire. After conquering the Achaemenid Empire in 328 BC, they began to invade northern India in 327. This was followed by his last major battle, the Battle of Hydaspes. It is now known as the Battle of the Hydaspes because it took place on the banks of the Hydaspes (formerly Indian Jhelum) in Punjab, Pakistan.

The battle against Alexander the Great was fought by Porus, an Indian king who owned an area between the Jhelum and Chenab rivers. At that time, Alexander’s troops were on the other side of the river, consisting of 40,000 infantry and about 5,000 cavalry. King Porus had between 30,000 and 50,000 infantry. Horses, etc. 2000-4000; About 100 troops and 1,000 chariots were on standby.

At the beginning of the war, Alexander suffered more casualties than in previous battles. Attempts to cross the river were thwarted by the Indian king’s troops, who were ready to attack from where they could cross. It is not easy to cross the river when the water level is low, but it is necessary to wait until the end of the winter to get there and to have enough food for the waiting time.

Finally, Alexander the Great changed his strategy. He often ordered his troops in small groups to cross the river from one place to another without actually crossing the river. When the Indian army arrived, it withdrew several times. After the Indian side found out that this was not a real crossing, they deployed a small number of troops for 50 miles without any movement.
