It was more than 100 years ago in the middle of World War One, that a very unlikely sporting event was held -- as it took place on the battle field on Christmas Day. Troops from opposing sides laid down their arms, to play football. It was a time put differences aside. That moment was poignant, and in memory of that historic game, an invitational tournament was held with players under the age 12, and it involved countries that took part a century ago in the so-called War To End All Wars.
