Factory production in Leningrad during the siege?

[TheMarcksPlan]

Reading Barber and Harrison's "The Soviet Home Front 1941-45," I came across a reference to Leningrad factory workers during the siege (1,000 calories/day - yikes).

For how long and to what extent were Leningrad's factories productive during the siege? I remember reading elsewhere that KV tanks were rolling off the line and straight into battle but I assumed that would exhaustion of stocks already in Leningrad. Were the Soviets bringing industrial supplies over the ice road and via boat to sustain production in Leningrad? Seems pretty ruthless if so...

Small arms, mortars, ammunition. There were apparently some stocks of materials which were sufficient for limited production. See the known example:

Another piece of equipment of particular interest: a Soviet copy of a German Nebelwefer heavy rocket was designed and produced in Leningrad beginning from 1942 as M-28 rocket (280-mm).
For production of KV tanks see:

Last batches were finished in October 1941. Yet there were tank repair facilities which continued working during the siege.

Any war is impossible without a map — and begins with a map...

In September 1943, the Leningrad cartographic unit (located at the address Buckle, 5, in the building of the famous cartographic institution Ilyin) received an order from the headquarters of the Supreme command: to begin creating a detailed plan of the city of Berlin on a scale of 1:5000. For the announcement of the order, the staff was gathered in the courtyard of the building. Staff cartasi, well sozdavalsya, why the need for such a plan, immediately called him a Map.

Topographic maps become obsolete quickly in peaceful days and even more rapidly — during the war. To make an accurate plan of Berlin for a year and a half before the end of the war, in the besieged Leningrad - an incredible task! To obtain information, we used aerial reconnaissance data: since 1941, all aircraft flying to bomb Berlin, necessarily had the appropriate equipment. In the course were plans for Berlin, maps and tourist brochures published in Nazi Germany, postcards, photos…

Workers of the cartographic part recreated the map literally bit by bit. The pre-war plan of Berlin scale 1:10000 cut into decimeter fragments, which were distributed to cartographers-draftsmen. Each of them brought its site to the desired scale in accordance with the geographical coordinates. More than 6,000 names of streets, squares, buildings, gates, bridges and other urban objects were carefully translated into Russian, so that any soldier could easily identify them on the ground. All the names were printed on paper strips, which were then cut out with filigree precision by cartographers with lancets and pasted each into its own square. Most of the objects were numbered: 151 — the Ministry of aviation, 152 — the Gestapo, 153 — the Reich Chancellery, Hitler's rate, 105 — the Reichstag. On the plan of Berlin were reflected in detail not only the streets, houses and urban facilities, but also the maximum strength of the bridges, which will have to pass the Soviet armored vehicles…

The cartographers, exhausted by the blockade, worked in very difficult conditions. They had to lift 50-kilogram bobbins to charge special photographic equipment, literally manually pull out of the Neva huge blocks of ice for cooling printing machines. During the air RAID, the staff of the cartographic unit did not even go down to the shelter — it took too much time to remove everything necessary for work.

In January 1944 a plan of Berlin was transferred to the Kremlin. In the early spring of 1945, the mobile cartographic printing house of the General staff (the so-called train № 1) printed the map of Victory and delivered it to the military units of the first Belarusian front, departing to the West.

Any war starts with a map and ends with it!

A smaller copy of the famous victory Map you can see at the exhibition "Great battles in maps and plans" in Pashkov's House, in the cartographic Department of the RGB from may 4 to 27, 10:00-18:00, every day except Sunday.

Next to the victory Map there are other interesting exhibits. For example, the Berlin plan, published in Germany in 1945, which already shows the boundaries of the occupation zones of the city, formed by the victorious countries in accordance with the decisions of the Yalta conference, and divided into similar zones map of the whole of Germany. At the exhibition you can see the postwar maps: "the Victory of the Soviet Armed Forces in the great Patriotic war of 1941-1945" (created in 1952) and the anniversary version of the 40th anniversary of the victory.
