John de Derby of Horsley was arrested because he and others came to the priory of Breadsall Park on Tuesday 18 June 1381, and made an attack on the prior and canons there, and imprisoned them there, and feloniously burnt and set fire to their houses there, namely the church, the kitchen and the chambers. He produces a pardon and goes free.
On 18 June 1381 John de Derby and others went to the lord king's castle of Horston and seized the said castle by force and held it; and they fixed and placed a certain banner of St George above the castle, seizing royal jurisdiction to themselves in prejudice to the lord king's crown and to the terror of the whole country. He produces a pardon and goes free.
