Here are some pictures of tree graffiti carved by bored GI's during both World Wars. The pictures were taken a few years ago but the trees are still there a tangible living link with the past.
This site was used during WW1 as a field camp for US troops before they were transported to the South coast ports for shipment to the Western Front. The first two pictures show three early WW1 US dog tags that were all found there. The first picture of tree carving is a link to those days being dated 31 OCT 1918 (just 11 days before hostilities ceased).
Again during WW2 the area was used by US troops before D Day and later a small hospital was set up for casualties evacuated from the fighting in North West Europe.
I did also find a selection of spent cartridge cases and buttons from that conflict. When reading the graffiti, it always strikes me that they seem to show a low level of education in the troops, you'll notice the reversed 'S' etc. But they would have been children growing up through the 1930's depression so I doubt if much was spent on education when much of the population was relying on Government hand outs at soup kitchens.
Remember its always worth recording the past it's our history, so if you have any carved trees near you like this, you should get out and record them take some photo's or rubbings while they're still around.
I hope you enjoy the pictures.
