A letter describing the historic truce on the Western Front on Christmas Day in 1914 has been revealed for the first time.

Captain AD Chater of the 2nd Battalion Gordon Highlanders describes the moment when soldiers on both sides of the First World War left the trenches and met in no man's land before playing a historic football match.

The letter, recently passed to the Royal Mail by a relative of Capt Chater, reads: "Dearest Mother,

"I am writing this in the trenches in my "dug-out" -- with a wood fire going and plenty of straw it is rather cosy, although it is freezing hard and real Christmas weather.

"I think I have seen today one of the most extraordinary sights that anyone has ever seen. About 10 o'clock this morning I was peeping over the parapet when I saw a German, waving his arms, and presently two of them got out of their trench and came towards ours.

"We were just going to fire on them when we saw they had no rifles, so one of our men went to meet them and in about two minutes the ground between the two lines of trenches was swarming with men and officers of both sides, shaking hands and wishing each other a happy Christmas..."

Capt Chater also describes another meeting in no-man's land, writing: "We had another parley with the Germans in the middle. We exchanged cigarettes and autographs, and some more people took photos. I don't know how long it will go on for - I believe it was supposed to stop yesterday, but we can hear no firing going on along the front today except a little distant shelling. We are, at any rate, having another truce on New Year's Day, as the Germans want to see how the photos come out!"

Earlier this year, Royal Mail announced a five year programme of remembrance for the First World War.

The company launched a series of special stamps to commemorate the war that will be issued from 2014 to 2018. The first set of six stamps were issued at the end of July and feature striking imagery of memorials, artefacts and portraits of the beginning of the conflict, as well as newly commissioned artwork.

In December 1914, a special sorting office, called the Home Depot, was built to deal with mail to the troops.

With 2,500 employees, mostly female, the depot processed letters and parcels bound for the troops. At its peak 12 million letters and one million parcels were passing through the depot each week.
