This is a pretty good article from the BBC from 1998. The actual cite contains an audio clip of an interview years ago with Frank Richards who was a long service enlisted man in the old 23rd Regiment (The Royal Welch Fusiliers) discussing the event.
The Christmas truce
http://news.bbc.co.uk/1/hi/special_report/1998/10/98/world_war_i/197627.stm
The Christmas truce of 1914 really happened. It is as much a part of the historical texture of World War I as the gas clouds of Ypres or the Battle of the Somme or the Armistice of 1918. Yet it has often been dismissed as though it were merely a myth. Or, assuming anything of the kind occurred, it has been seen as a minor incident, blown up out of all proportion, natural fodder for sentimentalists and pacifists of later generations.
But the truce did take place, and on some far greater scale than has been generally realised. Enemy really did meet enemy between the trenches. There was for a time, genuine peace in No Man's Land. Though Germans and British were the main participants, French and Belgians took part as well. Most of those involved agreed it was a remarkable way to spend Christmas. "Just you think," wrote one British soldier, "that while you were eating your turkey, etc, I was out talking and shaking hands with the very men I had been trying to kill a few hours before! It was astounding!"
"It was a day of peace in war," commented a German participant, "It is only a pity that it was not decisive peace."
So the Christmas Truce is no legend. It is not surprising, however, given the standard popular perception of World War I, that this supreme instance of "All Quiet on the Western Front" has come to have something of a legendary quality. People who would normally dismiss that far off conflict of their grandfathers in the century's teens as merely incomprehensible, find reassurance, even a kind of hope, in the Christmas truce.
This was not, however, a unique occurrence in the history of war. Though it surprised people at the time - and continues to do so today - it was a resurgence of a long established tradition.
Informal truces and small armistices have often taken place during prolonged periods of fighting and the military history of the last two centuries, in particular, abounds with incidents of friendship between enemies.
In the Peninsula War British and French Troops at times visited each others lines, drew water at the same wells and even sat around the same campfire sharing their rations and playing cards.
In the Crimean War British, French and Russians at quiet times also gathered around the same fire, smoking and drinking. In the American Civil War Yankees and Rebels traded tobacco, coffee and newspapers, fished peacefully on opposite sides of the same stream and even collected wild blackberries together. Similar stories are told of the Boer War, in which on one occasion, during a conference of commanders, the rank and file of both sides engaged in a friendly game of football.
Later wars too have their small crop of such stories. It is rare for a conflict at close quarters to continue very long without some generous gestures between enemies or an upsurge in the 'live and let live' spirit. So the Christmas truce of 1914 does not stand alone; on the other hand it is undoubtedly the greatest example of its kind.
There are certain misapprehensions regarding the Christmas truce. One widely held assumption is that only ordinary soldiers took part in it; that it was, as it were, essentially a protest of cannon-fodder, Private Tommy and Musketier Fritz throwing aside the assumptions of conventional nationalism and thumbing their noses at those in authority over them.
In fact, in many cases, NCOs and officers joined in with equal readiness, while others truces were initiated and the terms of armistice agreed at 'parleys' of officers between the trenches.
There is also some evidence that while some generals angrily opposed the truce, others tolerated it and indeed saw some advantage in allowing events to take their own course while never for a moment doubting that eventually the war would resume in full earnest.
One other misapprehension about the truce calls for rebuttal. There has grown up a belief, even among aficionados of World War I, that the Christmas truce was considered to be so disgraceful and event, one so against the prevailing mood of the time, that all knowledge of it was withheld from the public at home until the war was over.
In fact, the truce was fully publicised from the moment news of it reached home. Throughout January 1915 numerous local and national newspapers in Britain printed letter after letter from soldiers who took part; in addition they ran eye-catching headlines ("Extraordinary Unofficial Armistice", "British, Indians and Germans shake hands"), and even printed photographs of the Britons and Germans in No Man's Land. Germany also gave the event press publicity, though on a smaller scale and for a shorter period of time.
Publishing a year later, Sir Arthur Conan Doyle in his history of 1914 called the Christmas truce "an amazing spectacle" and in a memorable description, saluted it as "one human episode amid all the atrocities which have stained the memory of the war".
The phrase sums up the attraction of the truce: it is the human dimension which means that this relatively obscure event in the fifth month of a 52-month war is still remembered and will continue to catch the imagination.
In a century in which our conception of war has changed fundamentally, from the cavalry charge and the flash of sabres to the Exocet, the cruise missile and the Trident submarine, the fact that in 1914 some thousands of the fighting men of the belligerent nations met and shook hands between their trenches strikes a powerful and appealing note. It is perhaps the best and most heartening Christmas story of modern times.
