The original 186th Rifle Division was an infantry division of the Red Army, formed just before the start of the Second World War, in the Ural Military District, based on the pre-September 13, 1939 shtat (table of organization and equipment). At the outbreak of war with Germany in June 1941 it was already moving west, and was soon assigned to the 22nd Army, which became part of Western Front on July 1. After the disastrous frontier battles this Front was attempting to defend along the lines of the Dvina and Dniepr Rivers, with the 22nd on the far right (north) flank. The division was initially quite successful in holding prepared positions near Polotsk, but was outflanked by German crossings elsewhere along the Dvina and forced to retreat. It became encircled west of Nevel, but was able to escape when Velikiye Luki was retaken on July 21. It held positions east of this city into late August when it was struck by a surprise panzer assault and largely overrun, which soon led to Velikiye Luki changing hands again. As the damaged division retreated in late September a former militia division in the far north was assigned the same number, and this anomaly persisted into late June 1943, when the later division was redesignated. The 186th, now in Kalinin Front, took part in the winter counteroffensive which drove a huge salient into the German lines around Toropets, and created the Rzhev salient. By February 1942 the offensive had bogged down, and the following months saw attacks and counterattacks on the west side of the salient, during which the division was fortunate to escape encirclement. Prior to Operation Mars it was transferred to 39th Army, but it played only a minor role in that offensive, and was moved in March 1943 to the reserve near Moscow for rebuilding. When it returned to the fighting front in late April it joined 25th Rifle Corps under direct command of Bryansk Front. After Operation Kutuzov began this Corps came under command of 3rd Army to serve as an exploitation force. By the first week of August the 186th had fought forward to take part in the liberation of Oryol, after which it advanced through eastern Ukraine and into Belarus. During the fall and winter of 1943/44 the division fought in a series of offensives in eastern Belarus under command of Belorussian (later 1st Belorussian) Front, gradually closing in on the Dniepr. It was along this line at the start of the 1944 summer offensive and soon began advancing against the routed forces of Army Group Center, taking part in the capture of Babruysk and winning the Order of the Red Banner before continuing to drive westward. During this drive the division took part in the liberation of Brest, and was awarded its name as a battle honor. It was now in the 46th Rifle Corps of 65th Army, and it would remain under these commands into the postwar, moving to 2nd Belorussian Front in November. In September it forced crossings over the Narew River before the offensive was finally shut down. During the first phase of the Vistula-Oder offensive the 186th attacked out of the Serock bridgehead in the direction of Mława and Płońsk and two of its regiments were recognized for their roles in the fighting for these towns. Further awards followed for the division's role in the battle for Danzig in March. Beginning on April 18 it fought its way across both branches of the lower Oder River before advancing to the northwest. It took part in the fighting around Stettin, and in its final actions cleared the island of Rügen. After the war it was pulled back into Poland, where it was disbanded in June 1946.
