Answer: Alexander the Great had made plans for invading India, but his troops became mutinous and forced him back.
Explanation:
Alexander the Great had already conquered Persia, and had a very massive empire and very successful army. He had hoped to extend his empire into Asia, and so he would start doing that by attacking India. However, things became difficult as the Indian army was using elephants so Alexander's phalanx of soldiers started to be defeated. Thus, the troops became rebellious and wanted to not fight anymore.
