Gardiner Mitchell from Eglinton is bringing out a new edition of his book Three Cheers for the Derrys! in the autumn and anyone with information and photos of the 10th Royal Iniskilling Fusiliers has just four weeks to submit them for possible inclusion in the book.

Three Cheers was first published in 1991 and Gardiner has unearthed a wealth of new information to boost the volume's size by a third for the definitive 2008 edition. Copies of the original, which has become scarce, have been seen going for up to £130 on auction site eBay.

Gardiner is particularly interested to hear from anyone who can help him ascertain whether the soldier pictured beside this article is Reuben Orr, a young man who died at the age of 17 on 1st July 1916.

Reuben was the youngest soldier in the regiment and was too young to join up when he left these shores to fight for the Empire against Germany.

He came from Bond Street, his mother was widowed and he had no brothers or sisters. Is the young man in the photo Reuben?

Keen photographer Gardiner has digitally enhanced the many old photos included in the first edition and many new photos obtained in the intervening years will be seen for the first time.

"The photos in the new book are digitally enhanced so they look better than ever," he says.

"The book itself will remain the same, but there is loads of new information and new photos. The new edition will be a third bigger than the last.

"It is the last book ever to be written with first hand accounts from veterans of the great war. We know these images and information are out there.

"This is the last chance for people to submit new material, which must be first-hand, which may be included in the new book."

Gardiner hopes the new edition will be published in time for this year's remembrance day.
