When Napoleon read this letter, he said, "Let it be sent to the office of Foreign Affairs; it is an historical document." Madame Campan thus described a visit from the Czar of Russia: "A few days after the battle of Paris the Emperor Alexander came to Ecouen, and he did me the honour to breakfast with me.

After showing him over the establishment I conducted him to the park, the most elevated point of which overlooked the plain of St.Denis.

'Sire,' said I, 'from this point I saw the battle of Paris'-- 'If,' replied the Emperor, 'that battle had lasted two hours longer we should not have had a single cartridge at our disposal.

We feared that we had been betrayed; for on arriving so precipitately before Paris all our plans were laid, and we did not expect the firm resistance we experienced.' I next conducted the Emperor to the chapel, and showed him the seats occupied by 'le connetable' (the constable) of Montmorency, and 'la connetable' (the constable's lady), when they went to hear mass.

'Barbarians like us,' observed the Emperor, 'would say la connetable and le connetable.' "The Czar inquired into the most minute particulars respecting the establishment of Ecouen, and I felt great pleasure in answering his questions.
