|Italian bicycle troops|
It is hard to believe but bicycles were a relatively new invention at the outbreak of WW1. These are Italian troops who were bicyclists. It sounds odd but the use of taxi cabs to move troops to the front quickly turned the tide in defending France and saving Paris. One may laugh, but other than bicycles, these men would have been on horse, and a bike is much easier to maintain, does not need to eat and is a much smaller target.
