interpretation and conspiracy the said Joan, Nicholas, and Holy Church are like to be disinherited and put out of their estate and right, as is abovesaid, for ever, tortiously, against the said conditions, and contrary to the will of the said Peter [at More].

The ongoing border fights with Wales and Scotland were fought by England's feudal army. But for fighting in France, the king paid barons and earls to raise their own fighting forces. When they returned to England, they fought to put their candidate on its throne, which had been unsteady since its usurpation by Henry IV. All the great houses kept bands of armed retainers. These retainers were given land or pay or both as well as liveries [uniforms or badges] bearing the family crest. In the system of "livery and maintenance", if the retainer was harassed by the law or by enemies, the lord protected him. The liveries became the badges of the factions engaged in the War of the Roses. The white rose was worn by the supporters of the house of York, and the red rose by supporters of the house of Lancaster. Great lords fought each other for property and made forcible entries usurping private property. Nobles employed men who had returned from fighting in war to use their fighting skill in local defense.Henry IV was the last true warrior king. In both wars, the musket was used as well as the longbow. To use it, powder was put into the barrel, then a ball rammed down the barrel with a rod, and then the powder lit by a hot rod held with one hand while the other hand was used to aim the musket. Cannon were used to besiege castles and destroy their walls, so many castles were allowed to deteriorate. The existence of cannon also limited the usefulness of town walls for defense. But townspeople did not take part in the fighting.
