liv corps began its assault in the north on the seam of the soviet defence sectors iii and iv. the 'schwerer gustav' weapon continued to fire against ammunition dumps, which produced no effect. nevertheless, the 132nd infantry division was able to work its way up to the river. the 600 mm guns concentrated on the coastal batteries and "maxim gorky" fortress. meanwhile, the german 22nd infantry division attacked further to the east. some 200 soviet reinforcements of the 79th naval infantry brigade, protecting this sector, were lost in the bombardment, but the main defences held out. the brigade held most of its forces in reserve, while committing only a single company to cover the hilly terrain on the belbek river front. german assault groups breached the first and reserve lines by 08:15. the german forces had to negotiate heavily mined areas, slowing them down and allowing the soviet forces to make a partial recovery. supporting operations by the 50th and 24th german infantry divisions failed, which cost the wehrmacht 12 stug assault guns. the remote-control demolition units were not effective as the terrain was unsuitable.
