The Mallian campaign was conducted by Alexander the Great from November 326 to February 325 BC, against the Mallians of the Punjab. Alexander was defining the eastern limit of his power by marching down-river along the Hydaspes to the Acesines, but the Malli and the Oxydraci combined to refuse passage through their territory. Alexander sought to prevent their forces meeting, and made a swift campaign against them which successfully pacified the region between the two rivers. Alexander was seriously injured during the course of the campaign, almost losing his life.
