Furthermore, he had also smuggled 3,200 woolfells in March 1419. Feret appeared in the court of the Exchequer to defend himself ten days later, and admitted making shipments of the sarplers, 100 woolfells and 1,000 lambs’ pells, but asserted that he had had no intention of avoiding the staple at Calais. He was committed to the Fleet prison for two days, before being brought back on 23 Oct. to be questioned about the remainder of the earlier consignment.
