In the evening of 25 June, the German XLVII Panzer Corps cut between Slonim and Vawkavysk, forcing Pavlov to order the withdrawal of all troops in the salient behind the Shchara River at Slonim to avoid encirclement.
A second Red Army counter-attack by the 20th Mechanized Corps and 4th Airborne Corps failed to breach the encirclement as well, and by 30 June the pocket was completely closed.
