With him into England, of knights and squires,
Spearmen anote, and bowemen, and also arblasters.
Chaucer, too, describing a battlement, says—
And eke within the castle were
Springoldes, gonnes, bowes, and archers,
And eke about at corners
Men seine over the wall stand
Grete engines, who were nere hand,
And in the kernels, here and there,
Of arblasters great plentie were.
