Horrible war [I Am Interested In Ww1 and Ww2]

The 1914-1918 War was arguably the most horrible of all wars at least in my opinion. If a man was in a an infantry battalion and ordered into an attack, his chances of survival were about 80 to 20 against. Fliers in the RFC had an expected life span of 2 weeks. After 6 weeks they were veterans.
At times, 1 in 4 merchant ships crossing to or from the UK were torpedoes by submarines.
Hellish thing, war.
