He said that all he wanted from Britain was that she should acknowledge Germany’s position on the Continent. ... He concluded by saying that his aim was to make peace with Britain on a basis that she would regard as compatible with her honour to accept.

Within the next few days Marshal Zhukov was to launch the great Russian counteroffensive which began on December 6th. ... The turning point in the East had been reached: our hopes of knocking Russia out of the war in 1941 had been dashed.
