General William Tecumseh Sherman is now famous for two things: “marching through Georgia” and his statement that “war is hell”. Sherman led 95,000 men into Georgia in the spring of 1864. A year later, having fought their way to the Atlantic Ocean and then north through South Carolina, Sherman and his troops were in North Carolina when Lee surrendered to Grant at Appomattox. Later that month (after the assassination of President Lincoln), Confederate General Joseph Johnston surrendered to Sherman and the Civil War was finally over.
From Wikipedia: “Sherman’s bold move of operating deep within enemy territory and without supply lines is considered to be revolutionary in the annals of war….British military historian B. H. Liddell Hart famously declared that Sherman was ‘the first modern general'”.
Sherman’s goal was to end the war by destroying the South’s ability and desire to keep fighting, not by targeting the civilian population directly but by destroying as much crucial infrastructure as possible. From what I’ve read, he didn’t order the wholesale destruction of food supplies. Nevertheless, having his army “live off the land” had the same practical effect. Sherman understood the severity of his actions. This is from a letter he wrote to his wife In March 1864:
It is enough to make the whole world start at the awful amount of death and destruction…Daily for the last two months has the work progressed and I see no signs of a remission till one or both or all the armies are destroyed…I begin to regard the death and mangling of a couple thousand men as a small affair, a kind of morning dash – and it may be well that we become so hardened .
In September, after ordering the evacuation of Atlanta, he responded to complaints:
My orders are not designed to meet the humanities of the case, but to prepare for the future struggles in which millions, yea hundreds of millions, of good people outside of Atlanta have a deep interest. We must have peace not in in Atlanta but in all America. You cannot qualify war in harsher terms than I will. War is cruelty, and you cannot refine it; and those who brought war on our country deserve all the curses and maledictions a people can pour out….You might as well appeal against the thunderstorm as against these terrible hardships of war. They are inevitable, and the only way the people of Atlanta can hope once more to live in peace and quiet at home, is to stop the war, which can only be done by admitting that it began in error and is perpetuated in pride .
One of Sherman’s comrades, General Philip Sheridan, who led his own “scorched earth” campaign through the Shenandoah Valley, explained his actions this way:
The stores of meat and grain that the valley provided, and the men it furnished for Lee’s depleted regiments, were the strongest auxiliaries he possessed in the whole insurgent action….I do not hold war to mean simply that lines of men shall engage each other in battle, and material interests be ignored. This is but a duel, in which one combatant seeks the other’s life; war means much more, and is far worse than this.
Those who rest at home in peace and plenty see but little of the horrors attending such a duel, and even grow indifferent to them as the struggle goes on, contenting themselves with encouraging all who are able-bodied to enlist in the cause, to fill up the shattered ranks as death thins them. It is another matter, however, when deprivation and suffering are brought to their own doors. Then the case appears much graver, for the loss of property weighs heavily with the most of mankind – heavier, often, than the sacrifices made on the field of battle. Death is popularly considered the maximum of punishment in war, but it is not; reduction to poverty brings prayers for peace more surely and more quickly than does the destruction of human life .
A century later, the Geneva Conventions were modified to include the following prohibition:
It is prohibited to attack, destroy, remove, or render useless objects indispensable to the survival of the civilian population, such as foodstuffs, agricultural areas for the production of foodstuffs, crops, livestock, drinking water installations and supplies, and irrigation works, for the specific purpose of denying them for their sustenance value to the civilian population or to the adverse Party, whatever the motive, whether in order to starve out civilians, to cause them to move away, or for any other motive.
For any other motive, including ending a war.
A brief note: Grant and Sherman thought highly of General Johnston, one of their Southern adversaries. After the war, the three were close friends, and Johnston was a pallbearer at Sherman’s funeral.

There is a great collection of quotes from Sherman here, including these extremely prescient remarks he is said to have made in Louisiana before the war:
You people of the South don’t know what you are doing. This country will be drenched in blood, and God only knows how it will end. It is all folly, madness, a crime against civilization! You people speak so lightly of war; you don’t know what you’re talking about. War is a terrible thing!
You mistake, too, the people of the North. They are a peaceable people but an earnest people, and they will fight, too. They are not going to let this country be destroyed without a mighty effort to save it… Besides, where are your men and appliances of war to contend against them? The North can make a steam engine, locomotive, or railway car; hardly a yard of cloth or pair of shoes can you make. You are rushing into war with one of the most powerful, ingeniously mechanical, and determined people on Earth — right at your doors. You are bound to fail.
