The Royal British Legion in Mansfield will be commemorating the centenary of the outbreak of World War I at the beginning of next month.
The branch will hold the special ceremony at Mansfield Cemetery on 4th August, a century to the day that Britain declared war on Germany.
Starting at 6.30pm, a poppy cross of remembrance will be placed on each war grave of the conflict.
Janet Pierpoint, treasurer to the Mansfield branch, said: “Family members and descendants are warmly invited along with any members of the public who wish to attend and commemorate the special occasion .
“We will gather at the Cross of Sacrifice near the lower entrance of Mansfield cemetery.”
Britain had delivered an ultimatum to Germany on 4th August, 1914 after German troops invaded Belgium.
The Germans failed to respond.
The first shots between German and British forces were fired less than three weeks later in Belgium.
