First formation The 266th was first formed between 26 June and 2 July 1941 at
Kaluga in the
Moscow Military District as the 26th NKVD Mountain Division. It had a cadre of 1500 NKVD officers and men, and was to complete its formation as an NKVD unit by 17 July. By 2 July, it was transferred to the Red Army as the 266th Rifle Division, and consisted of the 1006th, 1008th, and 1010th Rifle Regiments, the 832nd Artillery Regiment, 557th Sapper Battalion, 379th Reconnaissance Company, and the 451st Truck Company. In early August, the 266th joined the
21st Army of the
Bryansk Front. It attempted to hold the southern flank of the front and counterattack against
Heinz Guderian's
2nd Panzer Group and the German
2nd Army south of
Smolensk. In late August, the 2nd Panzer Group advanced south across the
Desna River, breaking through the 21st Army. At this time the division was part of the army's
66th Rifle Corps and suffered heavy losses. It was disbanded on 30 August, but some of its units continued to fight under the army, and the division was still reporting its status to the army command as late as 14 September.
Second formation The 467th Rifle Division started forming in the
Stalingrad Military District on 14 December 1941. On 22 December the division was redesignated as the 266th Rifle Division at
Kuybyshev in the
Volga Military District. It included the 1006th, 1008th, and 1010th Rifle Regiments, as well as the 832nd Artillery Regiment, 360th Anti-Tank Battalion, 575th Sapper Battalion, 369th Reconnaissance Company, the 81st Anti-Aircraft Battery, 215th Communications Company, 295th Medical Battalion, and 451st Truck Company. After it was redesignated, the division was moved a short distance west to the
Volga River area near
Stalingrad. It remained there, forming and training under the Stalingrad Military District, until April 1942, when it was assigned to the
Reserve of the Supreme High Command (RVGK). In late April, the 266th joined the
Southwestern Front's
6th Army. On 12 May, when the Kharkov offensive in the
Second Battle of Kharkov began, the 266th was an assault unit and had the most success in its initial attacks. As a result, it was farther into the pocket when the German counterattack surrounded the army in the Izyum Pocket in late May. The division never made it out and the pocket was mopped up between 26 and 28 May. The 266th was officially disbanded on 30 May. Its former commander,
Alexander Tavantsev, was captured and became an officer in the
Russian Liberation Army.
Third formation The 266th was reformed for a third time on 26 August 1942 in
Kuybyshev Oblast, part of the
Volga Military District. It included the same basic order of battle as the previous formation. The division included 10,373 men, including cadres from the
Barnaul and
Saratov Infantry Schools, men from other Volga Military District units, convalescent wounded, and 780 non-commissioned officers and veterans transferred from the
Far Eastern Front. It was commanded by Major General
Leonid Vetoshnikov, a veteran of
World War I and the
Russian Civil War, who previously had been chief of the operations department of the
Southwestern Front. The 266th remained in the district until October, when it was assigned to the
4th Reserve Army in the
Reserve of the Supreme High Command. On 10 November, the division went to the front with the army, which became the
2nd Guards Army and was assigned to the Southwestern Front. Just before it fought in
Operation Little Saturn in December, the division included 10,163 officers and men, who were equipped with 7,229 rifles, 931 submachine guns, 250 light machine guns, 81 heavy machine guns, 188 mortars, 30 45mm anti-tank guns, and 44 76mm cannon or howitzers. The 832nd Artillery Regiment was formed without its authorized 122mm howitzers, and as a result was completely equipped with 76mm guns, like other divisions formed in mid-1942. Around this time the division transferred to the
3rd Guards Army's
14th Guards Rifle Corps. In late February 1943, the division was with the
5th Tank Army. By the end of March 1943, it was back with the 3rd Guards Army. After April, the 266th was part of the
32nd Rifle Corps. On 5 September, the division fought in the recapture of
Artemovsk during the
Donbass Strategic Offensive, and it was later awarded the honorific "Artemovsk". In late October, the army became part of the
4th Ukrainian Front. On 13 February 1944, the division was awarded the
Order of Suvorov, 2nd class. In late February, it was transferred to the
3rd Ukrainian Front's 6th Army with the 32nd Rifle Corps. The 266th became part of the
46th Army in March and transferred to front reserves in May. In June, it joined the
5th Shock Army. It fought in the
Second Jassy–Kishinev Offensive with the army and moved into the RVGK with the army in September. While in reserve, the 215th Communications Company was expanded into the 728th Communications Battalion and the 360th Anti-Tank Battalion was reequipped with
SU-76 self-propelled guns and became the 360th Self-Propelled Battalion. By 1 October, the division had a total of 80 guns and howitzers of all types, 72 82mm and 120 mm mortars, 12 SU-76s, 141 Anti-Tank rifles, and 374 machine guns. In late October, the division transferred with the
26th Guards Rifle Corps to the
1st Belorussian Front, where it fought for the rest of the war. In January 1945, during the
Vistula–Oder Offensive, the division loaded 30 men into each of its 18 US
2.5 ton trucks, added enough “collected vehicle” to motorize most of the 1006th Rifle Regiment heavy weapons, and used this improvised motor rifle force to support tank units pursuing retreating German troops across Poland. By this time most of the division artillery had been motorized with half-tracks, including both Lend-Lease US
M3A1s and captured German vehicles. The division fought in the
Battle of Berlin from April 1945. In the battle, it was with the 5th Shock Army's 26th Guards Rifle Corps, part of the 1st Belorussian Front. During the fighting in the
Oderbruch and the
Battle of the Seelow Heights in mid-April, the division was hit by friendly fire from its own artillery as it reached the tree line. The division ended the war with the honorifics "Artemovsk–Berlin Red Banner Order of Suvorov". == Postwar ==
