Peu après que les deux royaumes ont répudié la trêve de Leulinghem, ils commencèrent à lancer des raids le long de la frontière. Robert Stuart, 1erduc d'Albany et régent du royaume d'Écosse au nom de son frère Robert III, encouragea les raids écossais en Angleterre.
Le 22 juin 1402, une petite armée écossaise, revenant d'un de ces raids, fut battue par le comte de March, à Nesbit Moor.
