Excerpts from Books and Wikipedia
"The rebel leader was Henry Tudor. An exile living in Brittany, Henry's hereditary claim to the throne was tenuous, but he was the best candidate that Richard's opponents could find. . . . In a furious bid to seize victory with his own hands, Richard led a charge, slashing a path through the bodyguard of knights. . . . Richard was felled with an ax blow. Henry Tudor took the throne as Henry VII, and founded a dynasty that reigned for 118 years until the death of Queen Elizabeth I in 1603." [1001 Days]
