When Washington learned that certain officers were attempting to enrich themselves through various financial and political schemes, the commander in chief reminded his subordinates of the professional standards they should uphold.
"It is a matter of exceeding great Concern to the General, to find, that at a time when the united efforts of America are exerting in defence of the common Rights and Liberties of mankind, that there should be in an Army constituted for so noble a purpose, such repeated Instances of Officers, who lost to every sense of honour and virtue, are seeking by dirty and base means, the promotion of their own dishonest Gain, to the eternal Disgrace of themselves, and Dishonour of their country— practices of this sort will never be overlooked, whenever an Accusation is lodged, but the Authors brought to the most exemplary punishment."
George Washington, General Orders, 10 August 1775founders.archives.gov
