3. A Brilliant Piece of Deceit to Lull an Enemy Into Complacency
Alexander found himself in a standoff at the Hydaspes River, with an Indian army camped across the water from his own. If the Macedonians tried to cross, the Indians would be able to strike them at their most vulnerable mid-river. They could also fall upon and overwhelm a portion of Alexander’s on the Indian side of the river before the crossing was completed. So Alexander turned to a bit of brilliant deception to lull King Porus. The Macedonian marched his troops up and down his side of the river each day. The Indians vigilantly shadowed those movements at first. Over time, however, they became accustomed to them and grew complacent.
Alexander then quietly drew off the bulk of his army, and left behind a contingent to make noisy demonstrations in order to keep the Indians fixated on them. In the meantime, Alexander hurried to a crossing upriver, and safely got his force across the river, unopposed. Once on Porus’ side of the Hydaspes, Alexander advanced to attack him, and caught the Indians in a pincer. Porus’ army found itself between the main force under Alexander’s command, and the smaller contingent he left behind on the opposite side of the river to keep their enemy occupied. That contingent crossed the Hydaspes and fell upon the Indians’ rear and flank when they turned to face Alexander and the battle commenced. It was hard-fought, but the outcome was a total Macedonian victory, thanks to the successful deceit.
