Military strategies

The Civil War saw both sides employ a variety of strategies and tactics in order to gain the upper hand. The Union forces, led by General Ulysses S. Grant, employed a strategy of attrition, aiming to wear down the Confederate forces through a series of battles and sieges.

The Union forces also made use of the newly developed telegraph to coordinate their forces and communicate with their commanders.


On the other hand, the Confederate forces, led by General Robert E. Lee, employed a strategy of maneuver, attempting to outmaneuver the Union forces and exploit their weaknesses. They also made use of guerrilla tactics, such as hit-and-run raids and ambushes, to disrupt the Union’s supply lines. Both sides also made use of artillery and cavalry to support their infantry, and the Union forces made use of naval forces to blockade Confederate ports.

Grant and Lee

The Civil War was a conflict of unprecedented scale and complexity, and the generals who led the armies of the Union and Confederacy were instrumental in shaping its course. Chief among them were Ulysses S. Grant and Robert E. Lee.


Grant, a West Point graduate, had served in the Mexican-American War and had a successful career in the peacetime army. Lee, a Virginian, had been a career soldier since graduating from West Point and was widely respected for his tactical acumen.

Grant and Lee were both highly capable commanders, but their approaches to the war were markedly different. Grant was an aggressive leader, often willing to take risks and accept casualties when sending smaller forces in pursuit of victory. Lee, on the other hand, knew he had to force a decisive battle like Napoleon did at Austerlitz because he didn’t have the numbers for slow attrition warfare.

The Confederate military: organization and structure

The Confederate military was organized into three distinct branches: the Army of Northern Virginia, the Army of Tennessee, and the Army of the Trans-Mississippi. Each branch was commanded by a general and was responsible for defending its own territory.

The Army of Northern Virginia, commanded by Robert E. Lee, was the largest and most powerful of the three branches. It was responsible for defending the Confederate capital of Richmond and the surrounding area.

The Army of Tennessee, commanded by Braxton Bragg, was responsible for defending the western part of the Confederacy. Finally, the Army of the Trans-Mississippi, commanded by Edmund Kirby Smith, was responsible for defending the far western part of the Confederacy.

The Confederate military was also organized into divisions and brigades. Each division was commanded by a major general and was responsible for a specific area of operations. Brigades were commanded by brigadier generals and were responsible for a specific area of operations within a division.

However, the lack of a central command until late in the war made it difficult for the Confederacy to adopt a cohesive strategy.

The Unionist military: organization and structure

The Unionist military was organized and structured in a way that allowed for effective and efficient operations. The Union Army was divided into three main branches: infantry, cavalry, and artillery. Each branch was further divided into divisions, brigades, and regiments. The Union Army also had a separate medical corps, which provided medical services to wounded soldiers.


The Union Army was also organized into geographical divisions, with the Eastern, Western, and Trans-Mississippi departments. Each department was commanded by a major general, who was responsible for the operations within that region. The Union Army also had a centralized general staff, which was responsible for providing advice and guidance to the commanding generals.

Confederate diplomacy: attempts to gain international recognition

The Confederate States of America made several attempts to gain international recognition during the American Civil War. In 1861, the Confederate government sent diplomats to Europe, hoping to gain recognition from Britain and France. Despite their efforts, the Confederate diplomats were unable to convince either country to recognize the Confederacy.

The Confederacy also attempted to gain recognition from other countries, such as Mexico, Spain, and the Papal States. However, these efforts were largely unsuccessful due to the Union’s naval blockade, which prevented the Confederacy from trading with other countries, removing the incentive for other countries to recognise them. In the end, the Confederacy was unable to gain international recognition.

Confederate diplomacy: the importance of trade

The Confederacy was heavily reliant on trade for its survival. Its limited resources meant that it had to rely on imports from Europe and the Caribbean to sustain its war effort. This reliance on foreign trade was a major factor in the Confederacy’s strategy. It sought to secure diplomatic recognition from European powers, which would provide access to resources and markets.

The Confederacy’s efforts to secure diplomatic recognition were largely unsuccessful, but it was able to secure limited trade agreements with European powers. These agreements allowed the Confederacy to purchase arms and other supplies.

This trade was essential to the Confederacy’s war effort, as it provided a steady supply of resources and allowed the Confederacy to continue its fight. Without it, the Confederacy would have been unable to sustain its war effort and would have been forced to surrender much earlier.

The Anaconda Plan

The Union’s strategy to win the war was the Anaconda Plan. This plan was devised by General Winfield Scott and was designed to cut off the Confederacy from the rest of the world. The plan was to blockade the Confederate coastline, cutting off their access to international trade and supplies.

This would force the Confederacy to surrender due to lack of resources. The plan was also intended to divide the Confederacy into two parts, with the Union controlling the Mississippi River. This would prevent the Confederacy from trading with the western states, further weakening their economy.

The Anaconda Plan was a sound strategy, but it was difficult to execute. The Union had to maintain a blockade of the entire Confederate coastline, which was a difficult task. The Union also had to control the Mississippi River, which was a difficult task due to the Confederate’s strong presence in the area.

Despite these difficulties, the Anaconda Plan was successful in cutting off the Confederacy from the rest of the world and weakening their economy. This was ultimately a major factor leading to their surrender and the end of the Civil War.

The Confederate economy

The Confederate economy was a major challenge for the South during the Civil War. With the Union blockade of the Southern ports, the Confederacy was cut off from the global economy, making it difficult to acquire resources and supplies. To make up for this, the Confederacy was forced to rely on its own resources. This included the use of currency printing, taxation, and the impressment of goods and services.

The Confederacy also had to adapt to the changing nature of the war. As the war progressed, the Confederacy had to develop new strategies to make up for the lack of resources. This included the use of conscription, the use of railroads to move troops and supplies, and the use of guerrilla tactics. These strategies allowed the Confederacy to remain competitive despite the Union’s superior resources. Ultimately, the Confederacy’s ability to adapt to the changing nature of the war was a major factor in prolonging the conflict.

Vulnerabilities of the Confederacy

The Confederacy was at a disadvantage from the start of the war. Its population was smaller than that of the Union, and its economy was not as diversified. This meant that the Confederacy had fewer resources to draw on, and its army was not as well-equipped or well-trained as the Union’s.


Furthermore, the Confederacy was geographically divided, with its states spread out across the South. This made it difficult to coordinate military strategy and to move troops and supplies quickly.

The Confederacy also had to contend with the Union’s naval blockade, which prevented it from trading with other countries and receiving much-needed supplies. This blockade was especially effective in the later stages of the war, when the Confederacy was struggling to keep its armies supplied. The Union’s naval superiority was a major factor in the Confederacy’s eventual defeat.
