Dismayed by the number of soldiers and officers who applied for extended furloughs, Washington instructed his commanders to discourage such requests.
"The General hears with Astonishment, the very frequent Applications, that are made to him, as well by Officers as Soldiers for Furloughs: Brave Men, who are engaged in the noble Cause of Liberty; should never think of removing from their Camp, while the Enemy is in sight, and anxious to take every Advantage, any Indiscretion on our side may give them: The General doubts not, but the Commanding Officers of Corps will anticipate his wishes, and discourage those under them, from disgracefully desiring to go home, untill the Campaign is ended."
