the period between 8–12 june descended into a battle of attrition. several soviet counterattacks were repulsed with heavy losses. the german liv corps extended the salient on the seam of the iii and iv sector to 3 km, determined to break through before petrov could reinforce his lines. the 132nd infantry division cleared the haccius ridge while the 22nd infantry division overran most of the soviet 79th naval infantry brigade. the soviet unit tried counterattacking on 10 june, but was repulsed. the soviet formation was effectively destroyed, with the support of the luftwaffe, which used anti-personnel bombs against soviet infantry caught in the open. only one battalion (the soviet 1st batt./241st rifle regiment) was in a position to block the germans from encircling the "maxim gorky" fort. still, on 8 june liv corps had lost 1,700 men. in return, the lodgement in soviet lines was extended to 3 km deep and 5 km wide.
