Bishop John Kirkham, former bishop to the Armed Forces, led the commemoration service within the walls of the Armed Services Memorial in Alrewas. He said he did not find the occasion any easier since it began five years ago.
"I always find it a most moving occasion. It's very hard, I find very often, to talk to people.
"I feel deeply their grief and their sorrow. And to know what they must have gone through and what they must still be going through - something they have to live with forever.
"When they know they have lost someone young, so enthusiastic for what they were doing, and suddenly to know that they are no more with them here and are just united still by love. I find it very, very moving and quite upsetting."
