An unexploded WWII mortar was uncovered during routine cultivation works by farmers at Coldham in the Cambridgeshire Fens. The Police were called, who subsequently summoned an Explosive Ordnance Disposal (EOD) team from RAF Wittering to assess the item. The EOD team decided to dispose of the mortar in situ in a controlled explosion.
Parts of the Fens were used as practice firing ranges during WWII, with other areas of open land acquired on an ad hoc basis for military training exercises. As such, the mortar is one of the most commonly-found items of ordnance in the UK today.
