Napoleon won a series of victories against the Army of Silesia in the 10–15 February Six Days' Campaign, that gave him hope of better peace terms. After the 10 February Battle of Champaubert he sent instructions to Caulaincourt to "sign nothing". After a pause, negotiations at Châtillon resumed on 17 February but the change in Caulaincourt's behaviour convinced the allies that no negotiated peace was possible.
