Major General John Frederick Charles Fuller, was a 20th century British military officer, author, advocate of tank warfare and supporter and sympathizer of Nazism. Endowed with innovative ideas and focussed mind, Fuller was the actual mind behind the Wehrmacht’s Blitzkrieg tactics, George Patton’s rumbling and so on. He was the pioneering man who through his foresightedness and a modernistic approach became one of the founders of modern armoured warfare. A British Army officer, he served from 1899 until 1933, post which he took to being a military theoretician, war historian and a strategist. Till date, Fuller is best known for categorizing the principles of warfare. More than actually contributing in the field, Fuller thought about unconventional yet important things, such as how battles should be fought. It was due to this that he was different and unique from the rest. Despite his taste at failure, Fuller did not stop and gave his entire life on coming up with newer ideas on mechanized warfare. Not only were his ideas influential during the First World War, they were employed by the Germans in the Second World War as well. After his stint at the military, Fuller wrote books eventually turning into a military theoretician and war historian.
