In the spring of 326 BCE Alexander III of Macedon passed into the Punjab (at Ohind, 16 m. above Attock), using a bridge over the Indus constructed by Perdiccas and Hephaestion.
According to Quintus Curtius's History of Alexander the Great, Alexander went to the women's tent accompanied only by Hephaestion, counselor to the king and his intimate friend since the two had been children.
