War-time Londonderry as portrayed by US Navy artist

The images have not been seen in Londonderry since they were painted 70 years ago

Paintings by a US Navy artist, whose watercolours captured Londonderry during the height of the Battle of the Atlantic, will be put on display in the city for the very first time.

Dwight Shepler recorded events in Derry during October 1943.

The exhibit is part of a range of events to mark the 70th anniversary of the naval campaign.

The collection of 19 watercolours and charcoal drawings has not been seen in the city since they were painted.

The special exhibition will be held at the Base One Europe Museum at the Beech Hill Country House hotel.

Mark Lusby, a researcher with the Holywell Trust, said the discovery of the images was accidental.

"Holywell Trust is helping the volunteers in the Beech Hill Association to unpack this key part of Derry's history," he said.

"We discovered that some paintings of the US Navy in war-time Derry had been exhibited in Palm Beach in 1955 before being deposited in the US Navy archives."

The originals were deemed too fragile to bring to the city without major conservation work, so the US Navy Art Collection has provided high-quality digital copies.

During the war, Shepler served in Europe and the Pacific and was awarded a Bronze Star.

After returning home, he continued to paint and became the president of the Guild of Boston Artists.

The exhibition will be open from 10:00-17:00 BST on Sunday and entrance is free.
