(a) The main events of the Battle of Gettysburg [4 marks]

The Battle of Gettysburg, fought from 1 to 3 July 1863 in Pennsylvania, was the largest battle of the Civil War, involving over 160,000 soldiers. On the first day, Confederate forces under General Robert E. Lee drove Union troops through the town of Gettysburg onto the high ground of Cemetery Hill and Cemetery Ridge. On the second day, fierce fighting took place at locations including Little Round Top, the Peach Orchard and Devil's Den, where Union forces narrowly held their defensive positions. On the third day, Lee ordered Pickett's Charge: approximately 12,500 Confederate soldiers advanced across three-quarters of a mile of open ground against the Union centre on Cemetery Ridge, suffering devastating casualties from artillery and rifle fire. The attack was repulsed with enormous losses. Lee was forced to retreat to Virginia on 4 July, having lost approximately 28,000 men (killed, wounded and missing) compared to Union losses of approximately 23,000.

(b) Why the Battle of Gettysburg was a turning point in the Civil War [6 marks]

Gettysburg marked the last major Confederate offensive into Northern territory. Lee had invaded Pennsylvania hoping that a decisive victory on Northern soil would shatter Union morale and force Lincoln to negotiate peace. The failure of this invasion meant that the Confederacy would fight defensively for the remainder of the war, ceding the strategic initiative to the Union.

The Confederacy suffered irreplaceable losses of experienced soldiers, officers and equipment. Unlike the North, the South's smaller population and limited industrial capacity meant it could not replace its losses. Pickett's division, for example, suffered approximately 50% casualties and never recovered its strength.

Combined with the fall of Vicksburg on 4 July 1863 (which gave the Union complete control of the Mississippi River, splitting the Confederacy in two), Gettysburg shifted the strategic balance decisively. The twin defeats shattered Confederate morale and boosted Northern confidence at a time when war-weariness was growing and anti-war "Copperhead" Democrats were gaining strength. The battle also demonstrated that Lee, despite his tactical brilliance, could be defeated in a major engagement.

(c) How far was military leadership the most important factor in determining the outcome of the war? [10 marks]

Military leadership was an important factor. Robert E. Lee's tactical brilliance produced a series of remarkable Confederate victories, including Fredericksburg (December 1862) and Chancellorsville (May 1863), that kept the Southern cause alive despite inferior resources. However, Lee's strategic judgment was sometimes flawed: his decision to order Pickett's Charge at Gettysburg, sending infantry across open ground against entrenched positions with artillery, was a costly error that squandered irreplaceable manpower.

On the Union side, early commanders such as George McClellan proved over-cautious and reluctant to press advantages. The appointment of Ulysses S. Grant as overall Union commander in March 1864 brought a fundamental change in strategy. Grant understood that the North's advantage lay in its superior numbers and resources, and he pursued a strategy of continuous pressure, engaging Lee's army in the Overland Campaign of 1864 and refusing to retreat even after heavy losses at battles such as the Wilderness and Cold Harbor. William T. Sherman's March to the Sea through Georgia (November-December 1864) destroyed Southern infrastructure and shattered civilian morale, demonstrating that the Confederacy could no longer protect its own territory.

However, other factors were also crucial. The North's overwhelming material advantages, including a larger population, superior industry, a more extensive railway network and control of the seas through the naval blockade, made victory likely in a prolonged conflict. Lincoln's political leadership in maintaining public support, managing the war effort and making critical decisions such as the Emancipation Proclamation was essential. The Emancipation Proclamation itself provided additional manpower (180,000 African American soldiers) and prevented European intervention. Diplomatic factors, particularly the failure of "King Cotton" diplomacy to win European recognition for the Confederacy, deprived the South of crucial support.

On balance, military leadership was important, particularly Grant's ability to use the North's resources effectively and Lee's ability to prolong the war despite the South's disadvantages. However, it was one of several factors. Material advantages, political leadership, the Emancipation Proclamation and diplomatic isolation all played significant roles in determining the outcome.
