A report on Siege of Petersburg, American Civil War and Overland Campaign

As Commanding General, he led the Union Army to victory in the American Civil War in 1865 and thereafter briefly served as Secretary of War.

For thirteen months, Grant fought Robert E. Lee during the high-casualty Overland Campaign and at Petersburg.

The Battle of Cold Harbor was fought during the American Civil War near Mechanicsville, Virginia, from May 31 to June 12, 1864, with the most significant fighting occurring on June 3.

It was one of the final battles of Union Lt. Gen. Ulysses S. Grant's Overland Campaign, and is remembered as one of American history's bloodiest, most lopsided battles.

In the final stage, Lee entrenched his army within besieged Petersburg before finally retreating westward across Virginia.

Robert Edward Lee (January 19, 1807 – October 12, 1870) was a Confederate general who served the Confederate States of America in the American Civil War, during which he was appointed the overall commander of the Confederate States Army.

Grant engaged Lee's army in bloody but inconclusive battles at the Wilderness and Spotsylvania before the lengthy Siege of Petersburg, which was followed in April 1865 by the capture of Richmond and the destruction of most of Lee's army, which he finally surrendered to Grant at Appomattox Court House.

These battles in the Overland Campaign included the Wilderness, Spotsylvania Court House and Cold Harbor.

George Gordon Meade (December 31, 1815 – November 6, 1872) was a United States Army officer and civil engineer best known for decisively defeating Confederate General Robert E. Lee at the Battle of Gettysburg in the American Civil War.

In 1864–65, Meade continued to command the Army of the Potomac through the Overland Campaign, the Richmond–Petersburg Campaign, and the Appomattox Campaign, but he was overshadowed by the direct supervision of the general-in-chief, Lt. Gen. Ulysses S. Grant, who accompanied him throughout these campaigns.

General of the Army Philip Henry Sheridan (March 6, 1831 – August 5, 1888) was a career United States Army officer and a Union general in the American Civil War.

Sheridan arrived at the headquarters of the Army of the Potomac on April 5, 1864, less than a month before the start of Grant's massive Overland Campaign against Robert E. Lee.

A contrary view has been published by historian Eric J. Wittenberg, who notes that of four major strategic raids (Richmond, Trevilian, Wilson-Kautz, and First Deep Bottom) and thirteen major cavalry engagements of the Overland and Richmond–Petersburg campaigns, only Yellow Tavern can be considered a Union victory, with Haw's Shop, Trevilian Station, Meadow Bridge, Samaria Church, and Wilson-Kautz defeats in which some of Sheridan's forces barely avoided destruction.

The Battle of Spotsylvania Court House, sometimes more simply referred to as the Battle of Spotsylvania (or the 19th-century spelling Spottsylvania), was the second major battle in Lt. Gen. Ulysses S. Grant and Maj. Gen. George G. Meade's 1864 Overland Campaign of the American Civil War.

The armies then faced each other for nine months in the Siege of Petersburg.

Jubal Anderson Early (November 3, 1816 – March 2, 1894) was a Virginia lawyer and politician who became a Confederate general during the American Civil War.

Thus Early commanded the Confederacy's last invasion of the North, secured much-needed funds and supplies for the Confederacy and drawing off Union troops from the siege of Petersburg.

In one letter to Early, Lee requested information about enemy strengths from May 1864 to April 1865, the war's last year, in which his army fought against Lt. Gen. Ulysses S. Grant (the Overland Campaign and the Siege of Petersburg).

Pierre Gustave Toutant-Beauregard (May 28, 1818 – February 20, 1893) was a Confederate general officer of Louisiana Creole descent who started the American Civil War by leading the attack on Fort Sumter on April 12, 1861.

As Grant moved south against Lee in the Overland Campaign, Union Maj. Gen. Benjamin Butler launched the surprise Bermuda Hundred Campaign with landings up the James River.

Beauregard continued commanding the defenses of Petersburg in the early days of the siege, but with the loss of the Weldon Railroad in the Battle of Globe Tavern (August 18–21), he was criticized for not attacking more forcefully and he became dissatisfied with the command arrangements under Lee.

Ambrose Everett Burnside (May 23, 1824 – September 13, 1881) was an American army officer and politician who became a senior Union general in the Civil War and three times Governor of Rhode Island, as well as being a successful inventor and industrialist.

The IX Corps fought in the Overland Campaign of May 1864 as an independent command, reporting initially to Grant; his corps was not assigned to the Army of the Potomac because Burnside outranked its commander Maj. Gen. George G. Meade, who had been a division commander under Burnside at Fredericksburg.

After North Anna and Cold Harbor, he took his place in the siege lines at Petersburg.

The Western Theater of the American Civil War encompassed major military operations in the states of Alabama, Georgia, Florida, Mississippi, North Carolina, Kentucky, South Carolina and Tennessee, as well as Louisiana east of the Mississippi River.

Most of the initiatives failed: Butler became bogged down in the Bermuda Hundred Campaign; Sigel was quickly defeated in the valley; Banks became occupied in the ill-fated Red River Campaign; Meade and Grant experienced many setbacks and much bloodshed in the Overland Campaign before finally settling down to a siege of Petersburg.
