I dressed  myself  in  the  habit  of  a  Roman Catholic  priest,  and  at  about  one  o'clock in  the  morning  stole  out  of  the  garrison, passed  the  enemy's  lines,  and  arrived  in the  middle  of  their  camp,  where  I  entered the  tent  in  which  the  Prince  d'Artois  was, with  the  commander-in-chief,  and  several other  officers,  in  deep  council,  concerting a  plan  to  storm  the  fortress  next  morning. My  disguise  protected  me  so  well,  that  no one  thought  of  turning  me  out.  I  was able,  therefore,  to  hear  all  they  said  without  any  trouble.
