Sherman’s Letter To Atlanta: A Neglected Classic In American Military Thinking

The Long March

What the Gettysburg Address is to American political history, Major General William Sherman’s 1864 letter to the City Council of Atlanta is to American military history. It should be required reading for civilians and military professionals alike. Sherman’s gritty prose bridges the wild spirit of the frontier warfare of America’s past with its industrialized, idealistic future. Defining an “American way of war” has taken on a new urgency. As we consider our nation’s wars, present and future, Sherman’s letter is an underrated masterpiece.


Sherman’s plan to depopulate Atlanta of noncombatants and destroy its industrial capacity met resistance from the city’s residents. Sherman had none of it. “Now the war comes home to you you feel very different. You deprecate its horrors, but did not feel them when you sent car-loads of soldiers and ammunition, molded shells & shot to carry on war into Kentucky & Tennessee, desolate the homes of hundreds & thousands of good People,” he wrote. In his admonition of Atlanta’s city council, we hear echoes of America’s colonial frontier wars. Historian John Shy called those earliest conflicts “wars of annihilation.” For the first Americans, death by a random attack on an idle Tuesday was an everyday fear. Wars in that period were undertaken to wipe enemies out. Through celebrated military lore, the need to ground enemies into dust survived the Europeanization of the American military. Even in Sherman’s day, the rugged frontiersman was the romantic ideal of an American soldier.

Yet within this destructive vision, Sherman also casts an eye to the future. Sherman articulates a legal basis for the destruction. “Once admit the Union, once more acknowledge the Authority of the National Government, and instead of devoting your houses, and Streets and Roads to the dread uses of war. I and this army become at once your protectors, shielding you from danger let it come from what quarter it may.” Sherman’s war would be fought to reestablish the rule of law. Rather than a purely punitive campaign, the rebels only had to surrender and Sherman would be the first to welcome them back. Despite his aggressive rhetoric, during the March to the Sea Sherman ordered his commanders to avoid excessive force where it wasn’t needed. Unlike the war’s first years, Sherman also saw his application of military power as an extension of the people’s popular will: “I know that Such is the National Feeling. This feeling assumes various shapes, but always comes back to that of Union.”

The letter to the City Council of Atlanta can also be interpreted as a problematic document. Sherman’s contempt for the rebellion is on full display, and it can seem that he is relishing in war’s violence. While the idea of depopulating a city and laying waste to it is anachronistic, it bears noting that in some ideological quarters, Sherman’s violent message is celebrated. “War is cruelty, and you cannot refine it” he wrote to the City Council. “You might as well appeal against the thunder storm as against these terrible hardships of war.” To some, this sounds like a perfect policy statement.

Sherman’s Letter to the City of Atlanta mirrors its mercurial author. It also represents the articulation of a known turning point in American military history. Careful study of history is needed now. Unpacking a decade of failure while assessing future conflicts demands it. Civilian policy makers and mid-grade staff officers would do well to study the letter in detail while undertaking these historical case studies. How and why we fight is, after all, the basis of strategy. Something the United States hasn’t exactly excelled at.

GENEVA/DUBAI (Reuters) - U.S. President Donald Trump said he was prepared to take military action to stop Tehran from getting a nuclear bomb but left open whether he would back the use of force to protect Gulf oil supplies that Washington fears may be under threat by Iran.

Worries about a confrontation between Iran and the United States have mounted since attacks last week on two oil tankers near the strategic Strait of Hormuz shipping lane at the entrance to the Gulf. Washington blamed long-time foe Iran for the incidents.

Tehran denies responsibility but the attacks, and similar ones in May, have further soured relations that have plummeted since Trump pulled the United States out of a landmark international nuclear deal with Iran in May 2018.

Trump has restored and extended U.S. economic sanctions on Iran. That has forced countries around the world to boycott Iranian oil or face sanctions of their own.

But in an interview with Time magazine, Trump, striking a different tone from some Republican lawmakers who have urged a military approach to Iran, said last week's tanker attacks in the Gulf of Oman had only a "very minor" impact so far.

Asked if he would consider military action to prevent Iran from obtaining nuclear weapons or to ensure the free flow of oil through the Gulf, Trump said: "I would certainly go over nuclear weapons and I would keep the other a question mark."

Minnesota Gov. Tim Walz said Tuesday he is appalled by a state DFL Party staff member's tweet referring to the recently-launched USS Minneapolis-Saint Paul as a "murder boat."

"Certainly, the disrespect shown is beyond the pale," said Walz, who served in the Army National Guard.

William Davis, who has been the DFL Party's research director and deputy communications director, made the controversial comment in response to a tweet about the launch of a new Navy combat ship in Wisconsin: "But actually, I think it's gross they're using the name of our fine cities for a murder boat," Davis wrote on Twitter over the weekend.

NAVAL BASE SAN DIEGO — The trial of Navy SEAL Chief Eddie Gallagher officially kicked off on Tuesday with the completion of jury selection, opening statements, and witness testimony indicating that drinking alcohol on the front lines of Mosul, Iraq in 2017 seemed to be a common occurrence for members of SEAL Team 7 Alpha Platoon.

Government prosecutors characterized Gallagher as a knife-wielding murderer who not only killed a wounded ISIS fighter but shot indiscriminately at innocent civilians, while the defense argued that those allegations were falsehoods spread by Gallagher's angry subordinates, with attorney Tim Parlatore telling the jury that "this trial is not about murder. It's about mutiny."
