The plan is doubtless as good as another, but I doubt whether Talbot's force, if ten times as numerous as it is, could prevent Glendower from slipping away." That evening Oswald bought a supply of bread and meat, sufficient to last Roger and himself for three days.

Both had put on plain leather jerkins and cloth caps, and wore, underneath, their own suits with the Percy cognizance embroidered on them, in order that they might present themselves in proper attire, should they arrive at the king's camp.
