Had Chandragupta Maurya ever defeated Alexander the Great?

Based on what history tells us, Alexander the Great was never defeated by anybody. Chandragupta Maurya only succeeded in reclaiming territories that Alexander left in the care of his troops. Although, Chandragupta Maurya was a great fighter and he had thousands of soldiers under him.

History says Chandragupta Maurya had a special facility where weapons were being made, and this made him be a very strong force. He was able to fight with troops that were stationed to monitor Indian territories that were conquered by Alexander, and he won the battle. Going by history, Chandragupta Maurya never fought with Alexander. The only king that resisted Alexander was king Porus.

King Porus, together with other regional troops, fought with Alexander and resisted him to the point that it took bravery before Alexander was able to conquer them. To me, since the fight never happened between Alexander and Chandragupta Maurya, I don't think he defeated Alexander.

No, Chandragupta Maurya never defeated Alexander the Great. During the time that Alexander was at war with King Porus of India, the young Chandragupta Maurya was an exile from his country, and it is reported that he resided for a short time in the camp of Alexander the Great. There is a chance that he might have met the Emperor himself.

The revolt that Chandragupta Maurya initiated in India happened after Alexander had left the country. It was being controlled by the administration left behind by Alexander. It was after the death of Alexander the Great that Chandragupta Maurya was able to wrest control away from the generals and begin to turn the country back for India.

Chandragupta Maurya began to bring the country of India into one large unified state, instead of the smaller kingdoms it had been before. He was the founder of the Mauryan Empire, which grew to be one of the largest under his grandson, Emperor Ashoka.
