 Joseph Stalin was not pleased with the results of the first month of the Finnish campaign. The Red Army had been humiliated. By the third week of the war, Soviet propaganda was working hard to explain the failures of the Soviet army to the populace: blaming bad terrain and harsh climate, and falsely claiming that the Mannerheim Line was stronger than the Maginot Line, and that the Americans had sent 1,000 of their best pilots to Finland. Chief of Staff Boris Shaposhnikov was given full authority over operations in the Finnish theatre, and he ordered the suspension of frontal assaults in late December. Kliment Voroshilov was replaced with Semyon Timoshenko as the commander of the Soviet forces in the war on 7 January.
