At 7.30am, town clerk Helen Bojaniwska blew a whistle at the war memorial in Park Gardens to mark the centenary of the battle.
On July 1, 1916 at 7.30am, whistles blew along the Western Front as a signal to the troops to go “over the top”.
The small gathering observed the two-minute silence and stood quietly as two poems were read including Ivor Gurney’s On Somme.
Town Mayor Kevin Cranston said: “To share a few moments of our busy lives is the least that we can do for these remarkable young men who sacrificed so much for their country.”
Councillor Cranston personally marked the occasion though he was not in Stroud
for the ceremony. His paternal grandfather were one of the men to “go over the top” and survive.
