Jay MacBride has pointed me toward an amazing online database from the UK that includes the detailed service records of over 250,000 soldiers who fought between the years 1369 and 1453. Anyone with an interest in medieval history, especially military history, will find this database a veritable treasure trove of information. I'm frankly more amazed that this many records survive than I am that they're freely available online.
There's no question that this is a remarkable resource. Thanks again, Jay.
