After the Battle of Stalingrad, the pace of Goerdeler's conspiratorial activities gathered speed. Between November 1942 and November 1943, Goerdeler was in regular contact with his friends, the Wallenberg family of Sweden whom he used as middle-men in his efforts to make contact with the British and American governments. On January 22, 1943 at the home of Peter Yorck von Wartenburg Goerdeler met with the Kreisau Circle during which he argued and debated forcefully about the social and economic policies to be pursued by a post-Nazi government. Only with some difficulty were Ulrich von Hassell and Fritz-Dietlof von der Schulenburg able to patch up a measure of agreement between the Kreisau Circle and Goerdeler. Those present at the meeting of January 22 were Goerdeler, Hassell, General Beck, Johannes Popitz and Jens Jessens for the conservative faction and von der Schulenburg, Yorck von Wartenburg, Eugen Gerstenmaier, Adam von Trott zu Solz and Helmuth James Graf von Moltke for the left-learning Kreisau Circle. In March 1943, Goerdeler wrote a letter addressed to several German Army officers appealing to them to overthrow the Nazis and demanding that just one line divide Germans: "...that between decent and non-decent." Goerdeler went on to write: "How is it possible that so basically decent a people as the Germans can put up for so long with such an intolerable system? Only because all offences against law and decency are carried out under the protection of secrecy and under the pressures of terror" Goerdeler argued that if only a situation were created "in which, if only for twenty-four hours, it possible for the truth to be spoken again", then the Nazi regime would collapse like a house of cards.
