The Battle of Bosworth Field took place on the 20th of August 1485. Richard III rode from Nottingham to Leicester and joined Norfolk at the Blue Boar inn before the royal army proceeded westwards to intercept Henry's march on London.
Henry Tudor won the Battle of Bosworth Field by right of conquest after seizing the crown following the death of Richard III. He was proclaimed king at the top of Crown Hill near Stoke Golding after Lord Stanley found Richard's circlet.
The battle occurred near Ambion Hill south of the town of Market Bosworth in Leicestershire. The Yorkist army deployed on the hilltop along the ridgeline while Henry's force advanced past the marsh at the south-western foot of the hill.
Richard III commanded a Yorkist army that outnumbered Henry's forces with approximately 3,000 infantry in his centre group and around 4,000 men on Northumberland's left flank. Henry Tudor's force numbered between 5,000 and 8,000 men augmented by recruits gathered in Wales and English border counties.
King Richard III's corpse was stripped naked and strapped across a horse before being brought to Leicester where it was openly exhibited to prove he was dead. After two days the body was interred in a plain tomb within the church of the Greyfriars until archaeologists discovered remains under a car park in Leicester on the 12th of September 2012.
