General Lee's final attempt to fight Union forces near Appomattox Court House failed because Confederate troops were surrounded.

Explanation:

In April 1865, the Civil War, which had devastated the United States of America since its outbreak in 1861, was nearing its end. After 10 hard months of siege between Richmond and Petersburg, the Confederate Army of Northern Virginia left the trenches with the aim of going to meet with the forces still fighting in Northern Virginia, being quickly persecuted by the Unionist troops, who did not want let escape their emblematic opponent. After a series of encounters and skirmishes of varying importance, the Union Army managed to catch the Confederates near the town of Appomattox Court House.

At dawn on April 9, Confederate General Robert E. Lee launched an offensive to break the Unionist front thinking it was fully formed by cavalry, but when he realized that the riders of General Sheridan were supported by two infantry units and defeat in the Battle of Appomattox was inevitable, finally decided that the best option was to surrender its strength to General Ulysses S. Grant, who after surrendering Vicksburg in 1863 had led the Federal war effort.

Thus, that same April 9, 1865, General Robert E. Lee signed in Appomattox the surrender of the Confederate Army of Northern Virginia, the most emblematic of all those who fought for the Confederation; although its dissolution would not be formalized until the 12th, when soldiers and officers finally abandoned their weapons and peace arrived in Virginia. After this event it was only a matter of time before the other Confederate forces surrendered, ending the Civil War.
