After a series of skirmishes in the area of the villages of Zubryn, Kleszczówek and Gulbieniszki, the Lithuanian assault towards Kalwaria was repelled and driven northwards. However, the south-eastern front was broken in the area of Sztabin and Kolnica and by September 4 the Lithuanian army reached the outskirts of Augustów. Also the assault towards Sejny, a town located only some two kilometres from the Foch Line, was successful. By noon of September 2 near Berzniki the first skirmish was reported. A commander of Polish cavalry reconnaissance troop operating in the area was confident that the Lithuanian unit he encountered simply lost its way and approached it. However, his unit was quickly surrounded and disarmed. Soon afterwards a general assault on Sejny started. After several hours of heavy artillery barrage and fights on the outskirts of the town, it was repelled with negligible losses on both sides. Commander of the defending Polish 16th Uhlans Regiment, major Skrzynski, was confident that the fight around the city was a misunderstanding, so he asked for a cease fire.

The following days, the Polish forces from Sejny withdrew further southwards, to the area of Nowa Wies and Wigry lake. At the same time a counter-offensive along the Augustów-Sejny road was prepared.

Three battalions of Lithuanian infantry were surrounded and almost completely destroyed, while the remaining forces sounded the retreat. The counter-offensive was successful and on September 9 the Polish forces recaptured Sejny. The following day the Lithuanian forces were forced out to the other side of the Foch Line.
