A Watford soldier killed in Afghanistan has been featured in a new book honouring the lives and sacrifice of those who fought in the conflict.

Corporal Christopher Harrison, 26, died in May 2010 in an explosion while leading a patrol alongside the Afghan National Army through hostile territory in Sangin, Helmand Province.

Now tributes and memories of his time on the front line have been collected in war correspondent Graham Bound’s latest book, At The Going Down Of The Sun: Love, Loss and Sacrifice in Afghanistan, which went on sale on Tuesday to coincide with Remembrance Day.

Cpl Harrison's parents Martin and Gill, who live in Garston, hope the book will "preserve the memory" of their youngest son.

The former Lea Farm School and Parmiters' School pupil, who served in Bravo Company, 40 Commando Royal Marines, is one of 20 servicemen whose lives, from childhood to their untimely deaths, are featured in the new book.

Proud father Martin, 62, a retired quantity surveyor, said: "There is a whole chapter on Chris. It’s really our recollection of Chris and his childhood. His wife Rebecca also tells a bit about their marriage, and one of his best friends recollected what it was like for them fighting on the front line. The book is very much our story."

Martin, Gill and their elder son Russell, attended the book launch at Daunt Books in London on Monday evening.

Martin said: "The launch went very well and I see that the book was featured on 'Good Morning' on ITV. The launch was attended by many of the families of those featured in the book and various military personnel from all over the country."

Born in Watford, Cpl Harrison joined the Royal Marines in 2003.

He qualified as a heavy weapons (mortars) specialist and then completed his first tour of Afghanistan in 2007.

His second tour in the country began in January 2010 after Cpl Harrison successfully passed his Junior Command Training. He was based at Patrol Base Shuga at the time.

His wife Rebecca, who he married in 2008, lived with Cpl Harrison in Taunton, Somerset.

The family has donated a copy of the book to North Watford Library, and five more copies have been bought by Hertfordshire Library Service with one to be made available at Watford Central Library.
