Created by city artist Martin Waters, Fallen features more than 8,500 poppies donated by the Royal British Legion and members of the public.
The installation includes some flowers bearing the now unused inscription Haig Fund, which has its origins in a charity set up in 1926 by Field Marshal Douglas Haig, who commanded the British Expeditionary Force from 1915 until the end of the First World War.
“As well as a trench it also represents a mass grave, because I didn’t realise that some of the cemeteries where you see lots of individual crosses are actually mass graves,” said Mr Waters.
He has also created an accompanying display of wild poppies collected in Yorkshire which have been pressed into picture frames – one for each of the 435 UK military deaths in the Afghanistan war. However, he has since had to change the number on the card explaining the piece to 437, following the deaths of two soldiers from the 1st Battalion The Royal Gurkha Rifles on Tuesday.
At the rear of the church is a display called Remembered by ex-trawler skipper Ken Knox, which commemorates the trawlermen who aided the Royal and Merchant navies through mine-sweeping, submarine-hunting, rescues, tug work and other activities.
