* (51) As soon as peace is restored, we will remove from the kingdom all the foreign knights, bowmen, their attendants, and the mercenaries that have come to it, to its harm, with horses and arms
The Anglo-French War ended (with an English loss!) in 1214, but apparently there were still many mercenaries and foreign soldiers hanging out in England a year later. There was a need to expel them, primarily because having lots of bored militiamen hanging around isn’t conducive to domestic stability.
