The first attack was led on 4 March by the Soviet units of the
1st Belorussian Front and
2nd Belorussian Front; with first Soviet units entering the city around 0800, but was repulsed. On the same day, the nearby city of
Köslin (now Koszalin) fell and Soviets started to gather reinforcements to take Kolberg. On 6 March the Soviet High Command decided to turn the siege of the city from the Soviet forces to its Polish allies. By 8 March the Soviets received reinforcements in the form of the units from the
Polish People's Army, the
Polish First Army under the command of Polish-born general
Stanislaw Poplawski: the
6th, the
3rd Polish Infantry Division and support units. The Polish First Army was now tasked with taking the city; however their first attack was also repulsed. The German forces held stubbornly to the city, protecting the ongoing evacuation. Due to a lack of anti-tank weapons, German
destroyers used their guns to support the defenders of Kolberg. On 12 March a new assault was launched, with
heavy tanks, additional artillery units and the
4th Polish Infantry Division. The attack advanced but at the cost of very heavy casualties, and was broken off on 14 March. On 14 March, the Germans refused a Polish proposal to surrender. On 15 March the fighting resumed and the Germans received reinforcements from
Swinemünde (now Świnoujście) — the
Kell battalions. However, they failed to stop the Polish forces, which took the barracks, part of the railway station and the Salt Island. By 16 March the Germans pulled back most of their forces and concentrated on the defense of the port. The destruction of the
collegiate church in Kolberg after heavy artillery shelling by
katyushas allowed the Polish troops to breach the inner city. Polish forces assaulted the railway station (defended by a German
armored train Panzerzug 72A, which was destroyed on 16 March), pharmaceutics factory and the horse riding arena. On 17 March the Germans abandoned most of the defensive lines, leaving only a small number of troops to cover their retreat, and started to evacuate their main body of forces from the city. Polish forces took the railway station and reached the port, but most of the German troops managed to evacuate to Swinemünde (now
Świnoujście). The last German stronghold was in the fort built near today's lighthouse on the coastline. ==Aftermath==
