The battle was atypical in that it lasted for an entire day. Most battles at this time were decided in the first hour or two.
Thanks for the map, pix. We saw the Tapestry in Bayeux, it is wonderful, very moving. The French school kids were all there, celebrating France's LAST win. We few English-speakers were kind of grumbling ....
By the time of the Roundhead revolution, that had changed. Most of the decisive battles of that period were days long. Or sieges that lasted months!
So much decided at Hastings in so little time ...
