A field of 10,000 crosses marks the sacrifice made by men of the Royal Hampshire Regiment.
The tribute at the regimental museum has been unveiled to mark the 100th anniversary of the outbreak of World War One.
The regiment, which recruited heavily in the Portsmouth area, lost 8,023 soldiers in the 1914-18 conflict and 2,149 during World War Two.
The field outside the museum at Serle’s House in Winchester has been created as a temporary memorial to those who gave their lives.
The 10,000 crosses, planted by members of the Hampshire and Isle of Wight Army Cadet Force, will stay in place until mid-September.
Lt Col Colin Bulleid, of The Royal Hampshire Regiment Trust, said: ‘This is about commemorating the soldiers of the regiment who fought and died for us, not only in the First World War, but also during World War Two and conflicts beyond.”
The Hampshire Regiment, known as the Royal Hampshire Regiment from 1946, was an infantry regiment formed in 1881.
In 1992, ‘The Tigers’ were amalgamated into the Princess of Wales’s Royal Regiment.
