Military leadership in the American Civil War facts for kids

Kids Encyclopedia Facts

Military leadership during the American Civil War was handled by both political leaders and military generals. In the United States (the Union), the President was the top commander. He appointed political leaders to run the military departments. Most of the main Union commanders had experience in the regular army before the war. Some military leaders were volunteers, and a few even came from other countries.

In the Southern Confederacy, the President was also the commander-in-chief. He had studied at West Point and fought in the Mexican-American War. Many officers from the U.S. Army, who had trained at West Point, chose to join the Confederacy. Some important Confederate leaders came from state military groups, and like the Union, some were from other countries.

Union Army Generals

When the war started, the U.S. "Regular Army" was very small. It had only 1,080 officers and 15,000 enlisted soldiers. Even though many regular officers became Union generals, most stayed with their original units. However, most of the main Union commanders had served in the regular army before the war.

The top general of the U.S. Army changed during the war. The generals in charge were Winfield Scott, George B. McClellan, Henry Halleck, and finally, Ulysses S. Grant.

Many other important generals served the Union. Here are some of them:

Union Leaders from State Militias and Politics

Under the U.S. Constitution, each state was responsible for its own local military, called the militia. State governors appointed and promoted officers. After President Lincoln asked for 75,000 volunteer soldiers in April 1861, many state groups became known as United States Volunteers. This helped tell them apart from the regular army units.

Union generals could get two types of commissions: U.S. Army or U.S. Volunteers. Many generals held both types of commissions, but regular army rank was seen as more important.

Here are some leaders who came from state militias or political backgrounds:

Union Officers from Other Countries and Native American Leaders

The Union Army included soldiers and leaders from many different backgrounds. Some military leaders came from countries other than the United States.

Union Naval Leaders

The United States Navy grew very quickly during the Civil War. This helped the North greatly in blocking Confederate ports and shipping early in the war. The Navy started with an old fleet of 90 ships and lost many sailors to the Confederate Navy. However, a huge effort to build new ships, using new ideas from engineers like James Buchanan Eads and John Ericsson, helped the U.S. Navy become a powerful force.

Confederate Army Generals (Former U.S. Army Officers)

After the Southern states left the Union, many U.S. Army officers felt they had to be loyal to their home states. About 313 of these officers resigned from the U.S. Army and joined the Confederate Army. Confederate President Jefferson Davis, who was also a West Point graduate, valued these experienced officers highly. He made sure they were given important leadership roles.

Here are some of these former U.S. Army officers who became Confederate generals:

Confederate Leaders from State Militias and Politics

In the Southern states, there was a strong tradition of state military groups, especially in areas that were once frontier lands. Many important Confederate military leaders came from leading these state units.

Confederate Officers from Other Countries and Native American Leaders

No foreign countries sent troops to help the Confederacy directly. However, some military leaders in the Confederate army came from other nations.

Confederate Naval Leaders

The Confederate Navy did not have many places to build ships. Instead, they often used captured ships or bought warships from Great Britain. The South had many rivers that ships could use. However, after the Union built a large fleet of gunboats, they quickly took control of rivers like the Mississippi and Tennessee. This made these waterways almost useless to the Confederacy.

The Confederates did take over some Union Navy ships in harbors after they left the Union. They turned a few of these into ironclad ships, like the CSS Virginia. Ships called blockade runners were built and operated by British companies to get supplies past the Union blockade. Later in the war, the Confederate Navy operated some of these. A few new ships were built or bought in Britain, such as the CSS Shenandoah and the CSS Alabama. These warships attacked commercial ships, causing a lot of damage.
