Some time after the allies began mobilising, it was agreed that the planned invasion of France was to commence on 1 July 1815, much later than both Blücher and Wellington would have liked, as both their armies were ready in June, ahead of the Austrians and Russians; the latter were still some distance away.
Mõni aeg pärast liitlaste mobilisatsiooni algust lepiti kokku, et kavandatud sissetung Prantsusmaale algab 1. juulil 1815, palju hiljem, kui nii Blücher kui ka Wellington oleksid tahtnud, kuna mõlema armeed olid juunis valmis, austerlastest ja venelastest ees; viimane oli veel üsna kaugel.
