Military leadership in the American Civil War facts for kids

Kids Encyclopedia Facts

Military leadership in the American Civil War was vested in both the political and the military structures of the belligerent powers. The overall military leadership of the United States during the Civil War was ultimately vested in the President of the United States as constitutional commander-in-chief, and in the political heads of the military departments he appointed. Most of the major Union wartime commanders had, however, previous regular army experience. A smaller number of military leaders originated from the United States Volunteers. Some of them derived from nations other than the United States.

In the Southern Confederacy, the constitutional commander-in-chief was educated at West Point and had served in the Mexican War. Many officers in the United States Army, most of them educated at West Point at the expense of the United States, and having taken an oath of allegiance to the same, joined the rebellion against it. Several significant Confederate military leaders emerged from state unit commands. Some military leaders derived from countries other than the United States.

Civilian military leaders

President Abraham Lincoln was Commander-in-Chief of the Union armed forces throughout the conflict; after his April 14, 1865 assassination, Vice President Andrew Johnson became the nation's chief executive. Lincoln's first Secretary of War was Simon Cameron; Edwin M. Stanton was confirmed to replace Cameron in January 1862. Thomas A. Scott was Assistant Secretary of War. Gideon Welles was Secretary of the Navy, aided by Assistant Secretary of the Navy Gustavus Fox.

Regular Army officers

When the war began, the American standing army or "Regular army" consisted of only 1080 commissioned officers and 15,000 enlisted men. Although 142 regular officers became Union generals during the war, most remained "frozen" in their regular units. That stated, most of the major Union wartime commanders had previous regular army experience. Over the course of the war, the Commanding General of the United States Army was, in order of service, Winfield Scott, George B. McClellan, Henry Halleck, and finally, Ulysses S. Grant.

Militia and political leaders appointed to Union military leadership

Under the United States Constitution, each state recruited, trained, equipped, and maintained local militia; regimental officers were appointed and promoted by state governors. After states answered Lincoln's April 15, 1861, ninety-day call for 75,000 volunteer soldiers, most Union states' regiments and batteries became known as United States Volunteers to distinguish between state-raiused forces and regular army units. Union brigade-level officers (generals) could receive two different types of Federal commissions: U.S. Army or U.S. Volunteers (ex: Major General, U.S.A. as opposed to Major General, U.S.V.). While most Civil War generals held volunteer or brevet rank, many generals held both types of commission; regular rank was considered superior.

Native American and international officers in Union Army

Reflecting the multi-national makeup of the soldiers engaged, some Union military leaders derived from nations other than the United States.

Union naval leaders

The rapid rise of the United States Navy during the Civil War contributed enormously to the North's ability to effectively blockade ports and Confederate shipping from quite early in the conflict. Handicapped by an aging 90 ship fleet, and despite significant manpower losses to the Confederate Navy after secession, a massive ship construction campaign embracing technological innovations from civil engineer James Buchanan Eads and naval engineers like Benjamin F. Isherwood and John Ericsson, along with four years' daily experience with modern naval conflict put the U. S. Navy onto a path which has led to today's world naval dominance.

Civilian military leaders

Jefferson Davis was named provisional president on February 9, 1861, and assumed similar commander-in-chief responsibilities as would Lincoln; on November 6, 1861, Davis was elected President of the Confederate States of America under the Confederate Constitution. Alexander H. Stephens was appointed as Vice President of the Confederate States of America on February 18, 1861, and later assumed identical vice presidential responsibilities as Hannibal Hamlin did. Several men served the Confederacy as Secretary of War, including Leroy Pope Walker, Judah P. Benjamin, George W. Randolph, James Seddon, and John C. Breckinridge. Stephen Mallory was Confederate Secretary of the Navy throughout the conflict.

Former Regular Army officers

In the wake of secession, many regular officers felt they could not betray loyalty to their home state, and as a result some 313 of those officers resigned their commission and in many cases took up arms for the Confederate Army. Himself a graduate of West Point and a former regular officer, Confederate President Jefferson Davis highly prized these valuable recruits to the cause and saw that former regular officers were given positions of authority and responsibility.

Militia and political leaders appointed to Confederate military leadership

The land of Davy Crockett and Andrew Jackson, the state military tradition was especially strong in southern states, some of which were until recently frontier areas. Several significant Confederate military leaders emerged from state unit commands.

Native American and international officers in Confederate army

While no foreign power sent troops or commanders directly to assist the Confederate States, some leaders derived from countries other than the United States.

Confederate naval leaders

The Confederate Navy possessed no extensive shipbuilding facilities; instead, it relied on refitting captured ships or purchased warships from Great Britain. The South had abundant navigable inland waterways, but after the Union built a vast fleet of gunboats, they soon dominated the Mississippi, Tennessee, Cumberland, Red and other rivers, rendering those waterways almost useless to the Confederacy. Confederates did seize several Union Navy vessels in harbor after secession and converted a few into ironclads, like the CSS Virginia. Blockade runners were built and operated by British naval interests, although by late in the war the C.S. Navy operated some. A few new vessels were built or purchased in Britain, notably the CSS Shenandoah and the CSS Alabama. These warships acted as raiders, wreaking havoc with commercial shipping. Aggrieved by these losses, in 1871 the U.S. government was awarded damages from Great Britain in the Alabama Claims.
