PLOEGSTEERT, Belgium — On the side of a wind-swept field covered with scorpion weed, a simple wooden cross marks a unique event in football history.
At its base, amid wreaths of poppies, lie a smattering of balls and various club pennants, all in remembrance of the Christmas Truce of 1914.
A century ago on Christmas Day, German and British enemies left their World War I trenches and headed into no man's land in a few scattered locations on the Western Front for an unofficial truce among soldiers. Some eyewitness accounts say they were highlighted by something as remarkable as a few football kick-abouts.
"Suddenly a Tommy came with a football," wrote Lt. Johannes Niemann of Germany, referring to a British soldier. "Teams were quickly established for a match on the frozen mud, and the Fritzes beat the Tommies 3-2."
If not fully-fledged matches, other soldier's diaries and various reports also spoke of balls being kicked about in friendship.
"A huge crowd was between the trenches. Someone produced a little rubber ball so of course a football match started," Lt. Charles Brockbank of Britain's Cheshire Regiment wrote in his diary, which is part of "The Greater Game" exhibit at the National Football Museum in Manchester.
The proponents of the sport have cherished that day as historic proof that there is little that can better bridge man's differences than football.
This Christmas, the British supermarket chain Sainsbury's has taken the idea and turned it into a blockbuster ad, showing opposing soldiers living the truce amid a football match at the center of the heart-tugging, some say sanitized, view of that Great War day.
