Some soldiers facing court-martial pled ignorance of the regulation they had violated. To prevent this, Washington ordered his officers to read aloud every General Order to their assembled troops each evening.
"There is reason to apprehend, that the General orders are not regularly published, to the Non Commissioned Officers, & Soldiers of the army; as pleading Ignorance of Orders, will not for the future be admitted in excuse of any delinquency: It is once more ordered, that the Adjutants of the several Corps, will be exact, in seeing the Orders, read every evening to the Men off duty, of their respective Corps, as they may depend upon answering, before a Court Martial, for any neglect in obeying this order."
George Washington, General Orders, 17 July 1775founders.archives.gov
