But the directors were driven by self-interest to new adventures abroad. Bonaparte was resolved not to sink into obscurity, and the directors were anxious to keep him as far as possible from Paris; they therefore sanctioned the expedition to Egypt which deprived the Republic of its best army and most renowned captain. Coveting the treasures of Bern, they sent Brune to invade Switzerland and remodel its constitution; in revenge for the murder of General Duphot, they sent Berthier to invade the papal states and erect the Roman Republic; they occupied and virtually annexed Piedmont. In all these countries they organized such an effective pillage that the French became universally hateful.
