Meanwhile Francis Huger was studying medicine in Vienna. Learning that Lafayette was a prisoner of war at the fortress of Olmutz near
Olomouc in Bohemia (now the Czech Republic), young Huger determined to rescue the international leader in 1794. Together with
Eric Bollman a private plot, involving letters written in
invisible ink, was hatched to liberate Lafayette. The caper was implemented on November 4, 1794. Although Lafayette was briefly liberated, he was disoriented and recaptured several days later by his enemies. The attempt failed and Huger was himself taken prisoner and joined his would-be prize in Olmutz. After eight months of solitary confinement as a security threat to Austria, Huger was paroled on condition that he return to the United States. ==Personal life==
