A commemoration of the Battle of the Somme and the Battle of Jutland will take place in the Square by the War Memorial on Sunday 7th August, starting at midday.
There will be re-enactment groups there, and vehicles from the Military Vehicles Trust, as well as Hay History Group and the Royal British Legion Riders. There will also be a stall raising money for the Poppy Appeal.
Leading the parade will be the Swansea Pipe Band, followed by the standards of various British Legion branches and military associations. There will also be a choir - Voices in Unity from Rhayader, and a brass band from Brecon.
The heart of the commemoration will be a ceremony in which 12 red roses will be laid at the foot of the War Memorial, one for each of the Hay and Cusop men who lost their lives at the Somme, and the midshipman who died at the naval Battle of Jutland. The organisers are hoping to track down descendents of the men who died, to lay the roses.
