DOT - Long-Term Fire Point of the Great Patriotic War. These pillboxes were part of the Rzhev-Vyazma defensive line. The boundary was a system of moves and trenches (the remains were preserved in the forest), supplemented by fire points, and had several levels. On this defensive line were placed high hopes, therefore, during its construction, which began in July 1941, a huge number of people were involved. People worked in any weather and even under enemy fire from the air. Among the builders of the defensive line, along with personnel specialists in military construction, a large number of civilians worked, including volunteers of communists and Komsomol members from other regions (Moscow, Kaluga, etc.), 75% of the construction workers were teenagers and women. Many came without warm clothes, and construction continued until October 1941, until the enemy came to this milestone. For this reason, it was not built in the planned volume, although most of it was built by that time. People were transferred to the construction of the Mozhaisk and Moscow defensive lines. Here, fighting began.
In the area of Rzhev, the advancing enemy managed to break through the constructed line. However, Mr. Ostashkov was not captured by the enemy. Ostashkov became a front-line city. A part of the boundary in the area of Lake Sig became the front line. Here stood the forces of the Western Front (22nd, 29th, 31st Army, Colonel-General ISKonev), occupying the line Ostashkov-Yelets-Sychevka by October 10, 1941.
From this place, the subsequent counter-offensive of our army began in the direction of the city of Andreapol and the city of Velikie Luki.
