noon the following day the fighting ended. Finland ceded the Karelian Isthmus and Ladoga Karelia, part of Salla and Kalastajasaarento, and leased the Hanko naval base to the USSR, but remained a neutral state, albeit increasingly leaning toward Germany (see Interim Peace). The consequences of the conflict were multiple: Although the Soviet Union gained new territories, the war pushed neutral Finland towards an accommodation with Nazi Germany. Furthermore, the invasion had revealed the striking military weaknesses of the Red Army. This prompted the Soviet Union to reorganize its military forces, but it also dealt yet another blow to the international prestige of the USSR. As a result of having suffered disproportionately high losses compared to the Finnish troops — despite a fourfold Soviet superiority in troops and nearly absolute superiority in heavy weapons and aircraft — the Red Army appeared to be an easy target, which contributed to Hitler's decision to plan an attack against the Soviet Union. Soviet official casualty counts in the war exceeded 200,000, while Soviet Premier Nikita Khrushchev later claimed the casualties may have been one million. Soviets take the three Baltic countries From the beginning, there was tension over the Soviets' moves in Estonia, Latvia and Lithuania, which were in the Soviet sphere of influence. All three governments were presented with Stalin's ultimatums threatening with war, and had no other choice but to sign a so-called "Treaty of defence and mutual assistance" which permitted the Soviet Union to establish a number of military bases on their soil. Nazi Germany advised them to accept the conditions. The three Baltic countries acceded to the Soviet demands and signed the "mutual assistance treaties" on September 28, October 5, and October 10, 1939, respectively (for 10 years for Estonia and Latvia and 15 years for Lithuania). The tension included the internment of a submarine crew in the Orzeł incident. On October 18, October 29, and November 3, 1939, the first Soviet troops moved into the military bases in Estonia, Latvia, and Lithuania under the treaties. The Soviet Union had expressed discontent with the three Baltic countries' leaning toward Britain and France, and the so-called Baltic Entente of 1934, which could have ostensibly been reoriented toward Germany, and later used it to accuse the Baltic governments of a violation of the "mutual assistance treaties" of the autumn of 1939.
