Croggen, croggen.

King Henry II. in one of his expeditions against the Welsh, attempted a passage over Offa’s-dike, at Croggen-castle, in Denbighshire; in which his soldiers were defeated, and many slain, with some circumstances of cruelty on the part of the Welsh; whence they were reproachfully termed Croggens; which word was also repeated in skirmishes, where the English has the advantage, in order to excite them to revenge, by the memory of that transaction.
