FORMER BBC war correspondent Kate Adie will officially open the Keep Military Museum's World War One trench exhibition.

The exhibition at the Dorchester museum is an interactive learning resource that has been built with the aid of a Heritage Lottery Fund grant of more than £50,000 and will be opened on Wednesday morning.

The exhibition will change and grow over the next four years as the nation marks the centenary of the Great War.

Also present at the opening will be Lord Lieutenant Angus Campbell and the niece of Birdie Loder, who was the sweetheart of Lance Corporal Horace Collier of Cerne Abbas.

The Keep has a photograph of Birdie and a letter written to her by Horace and her niece will tell how she kept his letter after he was killed and until her death on her mid 1980s.

The letter finishes 'yours until death'.

Horace was killed in action on October 13, 1914 in fighting north of Bethune.
