Bayeux Tapestry
The Bayeux Tapestry is history as written by the winners.  
William of Normandy (in northern France) crosses the
English Channel and triumphs at the Battle of Hastings in
1066, becoming William the Conqueror, King of England.
The Tapestry's dozens of panels each tell a different part of
the story.  This one shows how the Norman invasion fleet
carried horses as well as men.  Norman cavalry were an
essential part of William's military might.
Here are the Norman cavalry, having landed in England.

All photography of the original Bayeux Tapestry is prohibited, both video and
stills.  The pictures above were taken in the souvenir shop.
The Battle of Hastings was a bloody affair with an uncertain
outcome.  William rallied his forces, and won the day after a
Norman archer killed King Harold, leader of the English.  
The Bayeux Tapestry remains the primary source upon which
historians of this era rely, even to the present day.

One unanticipated consequence from William of Normandy
becoming King William I of England, was that English kings  
now had claims to French lands.  This led to centuries of
additional warfare between England and France, including
the Hundred Years War; until the English finally withdrew.
