There’s a Reason This WWI-Themed 2014 Christmas Advert Inspired by Real Events Has Gone Mega-Viral

100 years ago, on the Christmas Eve of 1914, a series of sporadic, unofficial truces spread across the front lines of those fighting in the trenches of World War One.

That moving moment is documented in a new advert by Sainsbury’s, a large supermarket chain in the U.K.

The cinematic masterpiece features soldiers cautiously abandon their trenches and exchange greetings with those with whom they had been fighting. In the nearly four-minute ad, the two sides compete in a soccer match before the soldiers walk back into their trenches and pull out gifts each had exchanged.

The video was published to YouTube on Wednesday and has since amassed more than 4 million views.

“This advert is wonderful. The best by far this year,” one individual commented. “It’s a marvel, it really is. Such a thoughtful and poignant message that everyone can get along and be nice to each other despite wars going on.”

“This is so amazing,” echoed another.

“The best part about this is that it really happened,” wrote one more individual.

The advert was made in coordination with the Royal British Legion. According to the supermarket, the proceeds for each chocolate bar featured in the ad will go to the organization to benefit the armed forces.
