The first attacks were carried out by Luftwaffe against airports, airfields, and Lithuanian cities (Kėdainiai, Raseiniai, Karmėlava, Panevėžys, Jurbarkas, Ukmergė, Šiauliai, and others). These attacks claimed the lives of some 4,000 civilians. Most of the Soviet aircraft were destroyed on the ground (322 airplanes were lost in air versus 1,489 destroyed on ground). The Germans rapidly advanced forward encountering only sporadic resistance from the Soviets near Kaltinėnai, Raseiniai, Šiauliai and assistance from the Lithuanians. In the Battle of Raseiniai, the Soviets attempted to mount a counterattack, reinforced by tanks, but suffered heavy losses. Within a week, the Germans sustained 3,362 casualties, but controlled the entirety of Lithuania. Soviet losses were heavy and not known precisely; the estimates put them at 12–15 divisions. The Red Army also lost numerous aircraft, tanks, artillery, and other equipment.
