What did Alexander the Great do when he reached Swat Valley?

Alexander the Great invaded and conquered the Swat Valley.

At school we learned that in 327 bc, even before the Buddhists came to Swat, Alexander the Great swept into the valley with thousands of elephants and soldiers on his way from Afghanistan to the Indus. The Swati people fled up the mountain, believing they would be protected by their gods because it was so high.

But Alexander was a determined and patient leader. He built a wooden ramp from which his catapults and arrows could reach the top of the mountain. Then he climbed up so he could catch hold of the star of Jupiter as a symbol of his power.
