I always admired Charles Schultz for bringing a bit of WWI history to the public light via the comic strip. Ah, Snoopy vs. The Red Baron. Lee and I are big Snoopy/Charlie Brown fans too.
There were such truces during other wars too including the Civil War. I always enjoyed listening to Shelby Foote's (rest his soul) tales of soldiers from the north and south, calling out to each other.
"Hey Yank!"
"What cha want Reb?" 
M-1 TALKING ABOUT A WW 1 MEMORIAL. I WOULD LIKE TO OFFER
ALL TO LOG ON TO THE WW 1 WE HAVE IN KANSAS CITY, MO. I THINK
IT IS THE ONLY ONE IN THE U.S.A. THE TOWER HAD A PERPETUAL GAS
FLAME THAT WAS ALWAYS ON BUT WHEN WW 11 WAS DECLARED IT
WAS TURNED OFF. NOW IT IS STEAM THAT COMES OUT WITH THE
RIGHT COLOR LIGHTS TO SIGNIFY FLAMES. HERE IS THE WEB----
---WWW.NWWWONE.ORG. IT SHOULD ALSO SHOW A REPLICA OF
FLANDERS FIELD, WITH OVER A THOUSAND POPPIES. SO WE, K.C. MO.
ALSO HAS ITS WW 1 MEMORIAL. ROCKY 
I have a brick on the WALK OF HONOR. Reads

No Rocky!! 
Very neat place Rocky! I hope to get a chance to visit some day. (In my uniform I'm free!)
No Rocky!!
Good for you, no need to make your brick easy to pronounce for us gringos!
In Flanders Fields,
In Flanders fields the poppies blow
Between the crosses, row on row
That mark our place; and in the sky
The larks, still bravely singing, fly
Scarce heard amid the guns below.
We are the dead. Short days ago,
We lived, felt dawn, saw sunset glow,
Loved and were loved and now we lie
In Flanders fields
Take up our quarrel with the foe:
To you, from failing hands, we throw
The torch; be yours to hold it high.
If ye break faith with us who die
We shall not sleep, though poppies grow
In Flanders fields
