Before the battles began, the Finns abandoned the bridgehead which they had occupied on the southern shore of Svir, when troop transfers to the Karelian Isthmus made it impractical to hold.

During the previous three weeks, the Finnish defenders had managed to delay and disturb the advancement of the enemy offensive, wearing down and eating away the sharpest edge of the Soviet attack.

Lack of reserves made it difficult for the Finns to respond to the attacks, but by evening they had succeeded in stopping the Red Army breakthrough attempt, apart from a 400 m wide section of the line which the Soviets held tight.

The Finnish Air Force also took part in the battle, bombing Red Army formations on the southeastern edge of Lake Nietjärvi.

At 22:30 that evening, the Finns began an artillery preparation which was immediately followed by an infantry assault along the trenches from both ends, using automatic rifles, hand grenades and flame throwers.

In the early morning of 17 July 1944, the Finnish units approaching the trench from both ends managed to link up with the help of the flame throwers.

[4] The Finns deployed a surprise element, inflicting heavy damage on enemy forces with very short half-minute or one-minute artillery barrages and counter-battery firing.

The efficient cooperation of the elements of the Finnish armed forces helped the Aunus Group to stop the Soviet Karelian Front's advance along the shores of Ladoga at the U-line.

The concentrated field artillery and mortar fire power played a vital role, as in many other critical combats during summer of 1944.

The Finnish defense had prevented the Red Army from advancing from the north side of Lake Ladoga into the battle stages of the Karelian Isthmus.
