Rehnskjold, commanding just 8,000 Swedes, attacked the vastly numerically superior force of a Saxon army with Russian and Polish auxiliaries. The Saxons collapsed, their cavalry riding off without firing a shot and their infantry throwing down their muskets and running. The Russians and Poles tried to make a stand but were overwhelmed in part by the retreating Saxons. The Saxons lost all their artillery.
For this victory Rehnskjold was made a Field Marshall and created a count.
Peter the Great, expected the Saxons as reinforcements. On hearing the news he immediately decided to retreat from Grodno. He sacrificed over 100 cannon which were pushed into the Neman and marched south-easterly towards Kiev.
