Ex-service veterans paraded on Sunday for the service in Ayscoughfee Gardens, Spalding, to mark the anniversary of VJ Day.
The Lord Lieutenant of Lincolnshire, Tony Worth, and dignitaries joined veterans including personnel from the Burma and Malaya campaigns.
Around 2,000 people poured through Ayscoughfee’s gates for a 1940s weekend and many hundreds watched the service that marked the end of hostilities in the Second World War 68 years ago.
Wally Tennant, from the Remembrance Association, said the service is held on the nearest Sunday to the signing of the treaty.
A newly refurbished plaque for The Royal Engineers was dedicated.
