Oh soldier soldier

We decided to go to Hidcote Manor gardens today along with the rest of the population of the West Midlands I think.
We parked in the village of Mickleton and walked up the Cotswold escarpment to enter the gardens from the back, and felt very smug to have walked when there was a huge queue to park.
On the way through the woods above Mickleton we saw this carving on a tree and an explanatory plaque nearby.

" During the First World War , Norton Hall near Mickleton was opened as a hospital for wounded soldiers. Among the patients were some Belgian men. One of them, Victor Joseph de Martelaere died and was buried at the Church of St Lawrence in Mickleton where his grave can still be seen. Another of the Belgian men, it is assumed, made his way into Bakers Hill Wood and carved this outline of a Belgian soldier. Although the inscription on his kepi is largely indistinguishable, it looks as if there are two initials followed by his name and the date 1917 "

I wonder how big the original carving was and how much it has grown.
