Question

One fact about world war one that is very unusual. (a fact that isnt well known)​

Answer 1

In World War 1 a fake Paris was built to fool the German pilots. Railways and road were built and were lit in mid-night to make an impression of the real Paris so that once any bomber may hit the Paris. i.e the fake one there may not happen any life loss, instead only fake buildings and railway lines may get hit.
