From Zeppelin bombings to plans to make explosives from conkers were some of the First World War events discussed during a Lynn lecture.
Paul Coleman was invited to give the Diana Bullock Memorial Lecture, which is part of the Lynn Town Guides Programme.
Mr Coleman, who had studied at the College of West Anglia under noted Lynn historian Dr Paul Richards, was introduced by the chair of the Town Guides, Lindsay Campbell.
During the talk in the town hall, Mr Coleman outlined how Lynn had been affected during the war.
Along with the well-known Zeppelin raids on the town, Mr Coleman also discussed how some of the town’s men had died after their boats were sunk by U-boats.
He also discussed how youngsters in the town answered the call to support the war effort by finding conkers, which were hoped to be used in explosives.
The guides’ 37th season gets under way on Friday, May 2, offering walks on Tuesday, Friday and Saturday afternoons. Full details and a brochure for the season are available at the Tourist Information Centre at the Custom House.
