Sherman's march to the sea. By F. O. C. Darley.
Bringing the “hard hand of war” to civilians — especially as practiced by Union forces in campaigns like Sherman’s March — sits at the uneasy intersection of morality, military necessity, and the evolving laws of war. The Lieber Code (General Orders No. 100, issued April 1863) provided a legal and ethical framework for Union conduct during the Civil War. It did permit certain harsh measures against civilians under the doctrine of military necessity, but also imposed limits and obligations to avoid cruelty for its own sake.
The Lieber Code recognized that war sometimes requires harsh treatment, including against civilians, if they support or aid the enemy. Key sections include:
Article 14: “Military necessity… consists in the necessity of those measures which are indispensable for securing the ends of the war.”
Article 15: Military necessity does not admit of cruelty, torture, or wanton devastation.
Article 17: It is lawful to starve the hostile belligerent, armed forces or civilians, to reduce them into submission — but only as a measure of necessity.
Article 44: Destruction of property is lawful if demanded by the necessities of war.
Sherman argued his actions were not cruel for cruelty’s sake, but necessary to shorten the war and reduce total bloodshed. He avoided mass killings and tried to maintain discipline, though looting and violence did occur.
Arguments for moral justification:
It was a lesser evil: harsh tactics avoided longer, bloodier battles.
It targeted infrastructure and morale, not mass murder.
It followed legal principles of military necessity as codified in the Lieber Code.
Arguments against:
Civilians, especially women, children, and the elderly, bore undue suffering.
The line between necessity and punishment blurred.
In practice, looting and sporadic personal violence violated the spirit, if not always the letter, of the Code.
The Lieber Code allowed the application of the hard hand of war to civilians under strict conditions of military necessity. Sherman’s actions were arguably within its bounds, though the morality remains debatable. The Code tried to humanize war within the brutal logic of total conflict — but in practice, it offered a legal cover for actions that tested the limits of ethical warfare.
The March created severe food shortages for both civilians and the Confederate army. Many homes, barns, and businesses were burned, though some private homes were spared, especially if their occupants did not resist. Public buildings, factories, and Confederate government facilities were often deliberately targeted. Although the march inflicted severe hardship on the civilian population through widespread destruction, it was not intended to be, nor was it officially conducted as, a campaign of deliberate personal violence against civilians. While civilians undoubtedly suffered as their homes, livelihoods, and communities were devastated by the march, the intent was to break the Confederacy’s ability to wage war rather than to deliberately harm the civilian population.
The extent of the damage was severe, and arguably, the South never fully recovered from its effects. The march inflicted an estimated $100 million (equivalent to billions today) in damage. Although Savannah was largely spared destruction when it surrendered without a fight, cities like Atlanta, Milledgeville, and Griswoldville suffered heavy damage. Thousands of enslaved people fled plantations to follow Sherman’s army, further disrupting the Southern economy and labor force.
While the campaign inflicted significant damage, especially to infrastructure and Confederate military resources, some myths have overstated the extent of civilian suffering and total devastation. While Atlanta was heavily damaged, Savannah was largely spared because it surrendered without a fight. Many towns along the march suffered property destruction, but not all were burned to the ground. There is no evidence of mass killings of civilians. While foraging was often aggressive and left many families struggling, Union soldiers were under orders to avoid unnecessary harm to noncombatants. While some private homes were burned, most destruction focused on railroads, factories, mills, and farms that supported the Confederate war effort. Some homes were looted or destroyed if resistance was encountered, but not all were systematically targeted.
In 1864, the convention that dictated the rules of war was The Lieber Code (1863): A set of military regulations issued by the U.S. during the Civil War, which influenced later international laws. Sherman’s March was within the law set by code, but it went right up to the line, thanks to certain exceptions and in some cases, beyond.
Let’s look at a few of its provisions and see what happened on the March.
Article 15
– Military necessity allows destruction of enemy forces and materials, but not cruelty for its own sake.
Sherman’s view: Destroying infrastructure, supplies, and morale was a legitimate strategy to shorten the war. He believed “hard war” would reduce bloodshed in the long run.
Technically adherent—Sherman could argue that all actions were militarily necessary. But looting and personal attacks on women, children, and the elderly can’t be defended by this clause.
Article 17
Sherman’s March can be defended under Article 17 of the Lieber Code as a harsh but lawful application of military necessity. However, it tests the limits of that doctrine
Article 17 of the Lieber Code does not explicitly allow the deliberate starvation of civilians. However, it does create legal and moral space for actions that may incidentally cause civilian suffering—if those actions are deemed necessary for military success.
“War is not carried on by arms alone. It is lawful to starve the hostile belligerent, armed or unarmed, so that it leads to the speedier subjection of the enemy.”
Therefore, by saying the idea was to hasten the end of the war, legally Sherman could say it was military necessity to starve women and children and the elderly. A great example of how Sherman went right up to the line of legality, but did not cross it.
Article 22
– The unarmed citizen is to be spared in person, property, and honor as much as possible consistent with military necessity.
Reality on the ground: Civilians were subjected to:Home invasions, looting, threats
Destruction of food, tools, personal items
Occasional physical violence and
unprosecuted sexual assault
Technically compliant only if military necessity is broadly interpreted. In practice, this principle was often undermined by lack of discipline, particularly among foraging parties (“bummers”).
Article 31
– A victorious army may appropriate supplies but must distinguish between military and private property
Sherman’s orders:
Special Field Orders No. 120 instructed foraging but prohibited personal pillaging and trespass.
Enforcement was inconsistent, and in practice, private homes and valuables were often looted.
Violated in practice, though Sherman issued technically legal orders. He at times turned a blind eye to violations, perhaps often, prioritizing momentum and morale. If foragers drove off an old lady’s cows, for example, this is not covered under the Lieber Code, unless that old lady was a military threat or assisting the war effort, or generally to hasten the end of the war. This is how Sherman could say he was working under the Lieber Code.
Article 44
– All wanton violence against persons, especially women and children, is prohibited.
No widespread directive or sanction for such violence from Sherman, but:
Documented instances of abuse, harassment, and some killings of civilians.
Rape likely occurred, though not prosecuted.
Not directly ordered, but tolerated through weak enforcement.
Article 51
– Military commanders must try to restore public order and protect persons and property in occupied areas.
Sherman’s army often left chaos in its wake—most notably the burning of Columbia, SC, where drunkenness, looting, and fire caused mass civilian displacement.
Technically breached—Sherman and his officers failed to control their troops in several instances.
One of the Lieber Code’s most crucial provisions is Article 22, which declares the importance of “the distinction between the private individual belonging to a hostile country and the hostile country itself.” Article 22 puts forward “the principle…. that the unarmed citizen is to be spared in person, property, and honor as much as the exigencies of war will admit.”
Key provisions of the Code on civilian property include:
Protection of Civilians: The code emphasizes the protection of civilian persons and property from military operations.
Prohibition of Destruction: It prohibits the destruction of civilian property unless absolutely necessary for military operations.
Respect for Private Property: The code instructs military personnel to respect private property and avoid unnecessary harm.
Articles 37, 38, 46 & 47.cover this area as well.
It’s anyone’s subjective interpretation as to whether or not what Sherman ordered, versus what was often carried out, fits within these precepts. Either way, it’s a very close call.
Lieber himself was uncertain how to apply the principles. Military necessity, Lieber wrote, “allows of all destruction of property, and obstruction of the ways and channels of traffic, travel, or communication, and of all withholding of sustenance or means of life from the enemy; [and] of the appropriation of whatever an enemy’s country affords necessary for the subsistence and safety of the army.” Rather than constrain hard war, such language helped to make it possible.

Examples of personal injury and attacks: There were documented instances of personal violence against noncombatants, especially theft, property destruction, intimidation, and some physical abuse. While not officially sanctioned, these acts occurred frequently enough to be a recognized part of the civilian experience of the march. They highlight the blurred line between “hard war” and civilian victimization and are critical to understanding the real human impact of Sherman’s campaign. These accounts show theft, intimidation, physical abuse, and psychological terror, though—as with all wartime narratives—some must be read with attention to context, bias, and verification.
What Is the Function of Rules of War?
Whether creating rules or laws to govern war is t one of history’s most painful and persistent tensions: the desire for moral restraint versus the brutal realities of war. Are the “rules” or “laws” of war phony? No, they’re not phony—but they are imperfect and often inconsistently applied. The laws of war, such as those codified in the Lieber Code (1863), the Hague Conventions (1899, 1907), and the Geneva Conventions (especially after WWII), are real legal instruments. They’re backed by treaties, military doctrine, and in some cases, courts (like the International Criminal Court).
These laws serve several purposes:
Limit unnecessary suffering, especially of civilians and prisoners.
Maintain some moral legitimacy—for both domestic and international audiences.
Prevent escalation into unbounded barbarism (e.g., genocide, torture as routine policy).
Set standards for holding individuals accountable (think of the Nuremberg Trials or modern war crimes prosecutions).
However: Enforcement is uneven, often dependent on power dynamics. Victors rarely face the same scrutiny as the losers. States violate them regularly, sometimes justifying actions as “military necessity.” Non-state actors may ignore them entirely. So yes, there is hypocrisy—but that doesn’t mean the rules are fake. They are aspirational boundaries in an inherently chaotic and destructive endeavor.
Is winning all that matters? Militarily, winning ends the war. But how you win shapes the peace—and your legacy. If “winning” alone were the only standard:
Atrocities would become normalized.
Reprisals would spiral, making wars bloodier and longer.
The legitimacy of power would corrode, both domestically and abroad.
History is full of cautionary tales: the legitimacy of power depends on how its used. Overly severe punishment of the losers leads to long-lasting enmity . For example:
· Sherman’s March was brutally effective, yet carefully (if controversially) calibrated under the laws of war at the time. It was one of the events leading to the Lost Cause.
· Our treatment of Native Americans especially as illustrated at Sand Creek was abominable: immoral and illegal. Our relations with our aboriginal brothers remain tense over a century later.
· The terms of the WW1 peace led almost directly to WW2.
· Nazi Germany won many early battles, but their brutality turned most of the world against them.
· The US offered Germany the Marshall Plan after WW2 while the Russian raped their way through the country. How has that turned out?
· The My Lai Massacre during Vietnam might have had no strategic benefit but inflicted lasting moral and political damage on the U.S. As did napalming villages randomly.
Ethics in war isn’t about being gentle—it’s about staying human. Even amidst destruction, maintaining rules is an act of defiance against the abyss. Its a false binary to offer either winning or being humane. A civilized nation tries to do both. How you win determines who you become and whether your victory can endure the peace that follows.
Summary
The Lieber Code was written to provide a moral framework to guide the conduct of modern war. In that sense, it was a humanitarian step forward and became the basis of modern rules of war set under the Geneva Conventions. However, General Sherman used a loophole to get around its application in the March to the Sea. It is arguable that this loophole was expressly inserted for this purpose.
