The great conquerer who never lost a battle, and took great pains to spread greek culture where ever he went from his entire empire and and ancient Middle East was the only one King Alexander the great.
Another possibility:
There are revisionist questions about Alexander's activity in India which are hard to dismiss out of hand. His deference to King Poros and restoration of his kingdom after allegedly defeating him, and then donating Alexander's own ally King Taxila's kingdom to him; the apparent subserveince in then fighting Poros' enemies for him; and then withdrawal out of India, raises the question of whether the Hydaspes battle was in fact a defeat of Alexander, or at best a stand-off, which Alexander had to make reparations for. It smacks of a cover-up rewrite of events in the official Macedonian account glorifying Alexander. We don't have hard evidence and this will remain an unanswered question unless we oncover some hard evidence, but the questions also remain.
