Mannerheim writes a letter to the German leadership explaining extensively and in detail the situation in Finland. The letter is in response to an earlier letter sent to Mannerheim by Wilhelm Keitel on behalf of Hitler. In this letter Wilhem Keitel implicitly recognizes the deterioration of the German forces.
Mannerheim emphasizes the difficulties produced by the war in Finland. Business and industry calls for demobilizing of older age groups from the army. However, Petroskoi and Karhumäki are going to be captured before the onset of winter, but on the Isthmus and Svir further advance will not be possible.
