Forgot to add the ransoming/burning of Chambersburg, PA right here in my own backyard...
Headquarters Army Of Northern Virginia
Chambersburg, Pa, June 7, 1863
General Order No. 73. The duties exacted of us by civilization and Christianity are not less obligatory in the country of the enemy than in our own. The commanding general considers that no greater disgrace could befall the army, and through it our whole people, than the perpetration of the barbarous outrages upon the innocent and defenseless and the wanton destruction of private property that have marked the course of the enemy in our own country. ... It must be remembered that we make war only on armed men, and that we cannot take vengeance for the wrongs our people have suffered without lowering ourselves in the eyes of all whose abhorrence has been excited by the atrocities of our enemy, and offending against Him to whom vengeance belongeth, without whose favor and support our efforts must all prove in vain.
The commanding general, therefore earnestly exhorts the troops to abstain with most scrupulous care from unnecessary or wanton injury to private property, and he enjoins upon all officers to arrest and bring to summary punishment all who shall in any way offend against the orders on this subject.
R. E. Lee, General
