The battle of the river Tigris was an engagement between the Diadochi Seleucus and the Antigonid general Nicanor, on the southern bank of the river Tigris in the year 311 BC. Nicanor was on route to recapture the city of Babylon from Seleucus, but he was defeated when Seleucus surprised him with an assault on his camp during the night, forcing Antigonus to cease hostilities with the other Diadochi, (Ptolemy, Cassander and Lysimachus) in order to concentrate his efforts on recapturing the city of Babylon himself.
