“Medieval battle records go online. The new website reveals which medieval soldiers rode the furthest. The detailed service records of 250,000 medieval soldiers – including archers who served with Henry V at the Battle of Agincourt – have gone online.

The database of those who fought in the Hundred Years War reveals salaries, sickness records and who was knighted.
The full profiles of soldiers from 1369 to 1453 will allow researchers to piece together details of their lives.
Thomas, Lord Despenser is the youngest soldier on the database, whose career began when he was aged just 12 in 1385. Elsewhere, the career of Thomas Gloucestre, who fought at Agincourt, can be traced over 43 years and includes campaigns in Prussia and Jerusalem”.
