waterways, including the Narva and Plyussa rivers. The bulk of the land in the region is forested, and large swamps inundate areas of low elevation. The effect of the terrain on operations was one of channelization; because of the swamps, only certain areas were suitable for large-scale troop movement. On a strategic scale, there was a natural choke point between the northern shore of Lake Peipus and the Gulf of Finland. The 45-kilometre-wide strip of land was entirely bisected by the Narva River and included large areas of wilderness. The primary transport routes, the Narva–Tallinn highway and railway, ran on an east–west axis near and parallel to the coastline. There were no other east–west transport routes in the region capable of sustaining troop movement on a large scale. Preceding actions On 14 January 1944, the Leningrad Front launched the Krasnoye Selo–Ropsha Offensive, aimed at forcing the German 18th Army back from its positions near Oranienbaum. On the third day of the offensive, the Soviets broke through German lines and pushed westward. The Army Group North evacuated the civilian population of Narva. Soviet aims By 1944, it was fairly routine practice for Stavka to assign new and more ambitious missions to its operating fronts while the Soviet Armed Forces were conducting major offensive operations. The rationale was that relentless pressure might trigger a German collapse. For the 1943/1944 winter campaign, Stalin ordered the Red Army to conduct major attacks along the entire Soviet-German front, in a continuation of the "Broad Front" strategy he had pursued since the beginning of the war. That was in line with his long-standing rationale that, if the Red Army applied pressure along the entire front, German defences were likely to break in at least one section. The Soviet winter campaign included major assaults along the entire expanse of the front in the Ukraine, Belorussia, and the German Panther Line, in the Baltic Sea region. Breaking through the Narva Isthmus, situated between the Gulf of Finland and Lake Peipus, was of major strategic importance to the Soviet Armed Forces. Success in the Estonian operation would have provided an unobstructed route to advance along the coast to Tallinn, forcing the German Army Group North to escape from Estonia for fear of getting cornered. For the Baltic Fleet, trapped in an eastern bay of the Gulf of Finland, Tallinn was the closest exit to the Baltic Sea. The ejection
