Napoleon's sister Elisa, though having now abandoned her Grand Duchy of Tuscany, had nevertheless not given up completely in attempting to salvage something out of the collapse of her brother's Empire. Having obtained from Murat - husband of her sister Caroline - the guarantee that he would obtain the consent of the Coalition he had just joined to her retention of the Principality of Lucca and Piombino in return for having rendered up Tuscany without a fight, she had, by the time of Bentinck's appearance at Livorno, retired to Lucca. Upon hearing of his landing, she sent a delegation to gain assurances that Murat's pact would be respected. Bentinck replied that it would not. If she did not depart immediately, he said, she would arrested. With 2,000 British troops dispatched towards the city to carry out this threat, the heavily pregnant Elisa had no choice but to abandon the last of her territories and flee north, where she eventually fell into allied hands at Bologna.
