In Virginia, Native American Pocahontas marries English colonist John Rolfe.
Indigenous Powhatan woman Pocahontas marries English colonist John Rolfe in Jamestown, forging a brief peace between Native Americans and colonists.
On April 5, 1614, Matoaka, known as Pocahontas, daughter of Chief Powhatan, wed tobacco planter John Rolfe in the Jamestown colony of Virginia.

Rolfe’s introduction of sweeter tobacco strains had already boosted the colony’s economy. Pocahontas traveled to England in 1616, hailed as a symbol of the “civilized savage” and unity between cultures. Her early death in 1617 solidified her place in folklore and colonial history.

American Civil War: The Battle of Yorktown begins.
The Battle of Yorktown begins the Union's Peninsula Campaign against Confederate defenses in Virginia.
On April 5, 1862, Union forces under Major General George B. McClellan commenced operations against Confederate defenses at Yorktown, Virginia.
The engagement marked the opening of the Peninsula Campaign, aiming to capture Richmond, the Confederate capital.
Union troops advanced along the York River, supported by naval gunfire from warships in Chesapeake Bay.
Confederate General John B. Magruder fortified the Warwick Line and used deceptive maneuvers to delay the Union assault.
McClellan's siege tactics brought heavy artillery into play but led to a protracted standoff rather than a swift victory.
After weeks of entrenchment, Confederate forces withdrew on May 4, 1862, buying time to reinforce Richmond's defenses.
The Battle of Yorktown thus became a pivotal moment, highlighting both the strengths and limitations of Union leadership.
