Which battle in 1460 resulted in the Yorkist capture of King Henry VI?

The Battle of Northampton in 1460 resulted in the Yorkist capture of King Henry VI. Fought on 10 July near the River Nene in Northamptonshire, it was a major Yorkist victory during the Wars of the Roses, the dynastic conflict between the houses of Lancaster and York.

The Yorkist army was led by Edward, Earl of March, who later became Edward IV, along with Richard Neville, Earl of Warwick, and William Neville, Lord Fauconberg. Henry VI's Lancastrian forces defended a fortified position near Delapré Abbey, but heavy rain made their artillery ineffective. A Lancastrian commander, Lord Grey of Ruthin, then changed sides, allowing the Yorkists into the camp.

The battle was brief but deadly for several leading Lancastrians, including the Duke of Buckingham, the Earl of Shrewsbury, Lord Egremont, and Lord Beaumont. Henry VI was found in his tent and captured by the Yorkists, who escorted him to London. The victory did not end the conflict: Margaret of Anjou and other Lancastrian supporters continued resistance, leading to further battles including Wakefield and Towton.
