In August 1805, not long before the War of the Third Coalition, France extended an offer of alliance to Prussia. It mainly consisted of Prussia taking Hanover in exchange for an offensive-defensive alliance. Russia was preparing troops to cross into Prussian territory on 28 September, with or without consent. In any event, King Frederick William III was not interested, despite Hardenburg and Brunswick's counsel. He even recalled Christian von Haugwitz, the anti-French former foreign minister to resume his position. One possible POD is for Haugwitz to die. One of his stated reasons for leaving was poor health (but it was clear professional embarrassment had much more to do with it). FW3 could start relying on the pro-French Hardenburg, sending Prussia into the French camp.
