Military leadership in the American Civil War

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 Republic who held the Grand Army under his Command 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 Union 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 Grand Army of the Republic, most of them educated at West Point at the expense of the State of the Union, 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.

Commander-in-Chief was never a Officer or Position held by an Officer of the United States Armed forces Though many fraudulent attempts have been made throughout history to unlawfully usurp and Divert the Constitutional Civil Authority over the National Militaries to the 1871 Corporate Officer/President through Propaganda Publishings beginning as early as Abraham Lincoln.	Abraham Lincoln	March 4, 1861 - April 15, 1865 (1,464 days during the war)	assassinated April 14, 1865; died April 15, 1865
	Andrew Johnson	April 15, 1865 - March 4, 1869 (24 days during the war)	Declared the armed conflict to be "virtually" ended on May 9, 1865 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.

Wool 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. Edward D.

Schoepf Carl Schurz Franz Sigel Régis de Trobriand Ivan Turchaninov 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.

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. Title Name Tenure Notes Commander-in-Chief Jefferson Davis February 18, 1861 - May 5, 1865 Vice President Alexander H.

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.

Patrick Cleburne Stand Watie Camille Armand Jules Marie, Prince de Polignac Raleigh E. Colston Collett Leventhorpe George St. Leger Grenfell 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.
