In 1944, the coup attempt yet to come the closest to success against Hitler, failed. Now, your mission is to plan, in detail if possible, a coup sometime between barbarossa and the end of the war, leading to the dismissal of the Nazi government.
To your help you have all the original conspirators, any others you think were likely candidates, as well as any disillusioned soldiers on leave near Berlin.
Do you think it is possible? Would it be possible earlier than 1944?
