During November 1939, Halder conspired with General Brauchitsch. Halder declared that he would support Brauchitsch if he were to try to curtail Hitler's plans for further expansion of the war, but Brauchitsch declined (the so-called Zossen Conspiracy). Brauchitsch and Halder had decided to overthrow Hitler after the latter had fixed "X-day" for the invasion of France for 12 November 1939, an invasion that both officers believed to be doomed to failure.[4] During a meeting with Hitler on 5 November, Brauchitsch had attempted to talk Hitler into putting off "X-day" by saying that morale in the German Army was worse than what it was in 1918. This statement enraged Hitler, who then harshly berated Brauchitsch for incompetence.[5] After that meeting, both Halder and Brauchitsch told Carl Friedrich Goerdeler that overthrowing Hitler was simply something that they could not do, and that he should find other officers if that was what he really wanted to do
