The "Battle of Crogen" (nprn 410131) does not seem to have been a battle, more one of a series of minor harassements of Henry II's army by the Welsh. The locations of the skirmishes are uncertain. However, a commemorative plaque to the event has been affixed to the road side of the east parapet wall of Castle Mill Bridge (nprn 310228) and refers to the "Battle of Crogen" having been fought "nearby in August 1165 . . . between Henry II, King of England (r.1154-89) and Welsh forces under Owain Gwynedd (1137-70)" The plaque was unveiled on 04 March 2009 by Wrexham Borough Council Leader Aled Roberts.
