Figure 8.8: At Towton the position of the two armies and the maximum possible frontage is defined by the constricted terrain, within which the battle archaeology fits remarkably well. On the northern (Lancastrian) side the scatter is just 800 m across, with a wide area on the east side of the field that lacks artefacts and may represent an area of brief cavalry action. On the southern (Yorkist) slope the width is 1,000 m, also with an eastern gap. The presence of two small calibre lead projectiles and two fragments of gun barrel on the north side of Towton Dale, within or very close to the arrowhead scatter, may suggests the latter is not simply an ‘artefact’ resulting from survival, deriving from mass graves. It may genuinely represent a key part of the action.
