He explored the business of fighting, in terms of the relationship between warfare and social, political, and economic factors in the civilian sector.

He served in the Second Boer War in South Africa from December 1899 to 1902,[2] and was promoted to lieutenant on 24 February 1900 a couple of months after arriving there.

[10] In the spring of 1904 Fuller was sent with his unit to India, where he contracted typhoid fever in autumn of 1905; he returned to England the next year on sick-leave, where he met the woman he married in December 1906.

After 1918, in January of which he was promoted to brevet lieutenant colonel,[14] he held various leading positions, notably as a commander of an experimental brigade at Aldershot.

Impatient with what he considered the inability of democracy to adopt military reforms, Fuller became involved with Sir Oswald Mosley and the British fascist movement.

[1] As a member of the British Union of Fascists (BUF), he sat on the party's Policy Directorate and was considered one of Mosley's closest allies.

Like Fuller, theorists of Blitzkrieg partly based their approach on the theory that areas of large enemy activity should be bypassed to be eventually surrounded and destroyed.

Blitzkrieg-style tactics were used by several nations throughout the Second World War, predominantly by the Germans in the invasion of Poland (1939), Western Europe (1940), and the Soviet Union (1941).

While Germany and to some degree the Western Allies adopted Blitzkrieg ideas, they were not much used by the Red Army, which developed its armored warfare doctrine based on deep operations, which were developed by Soviet military theorists Marshal M. N. Tukhachevsky et al. in the 1920s based on their experiences in the First World War and the Russian Civil War.

Fuller frequently praised Adolf Hitler in his speeches and articles, once describing him as "that realistic idealist who has awakened the common sense of the British people by setting out to create a new Germany".

[20] On 20 April 1939, Fuller was an honoured guest at Hitler's 50th birthday parade, watching as "for three hours a completely mechanised and motorised army roared past the Führer."

Vaughan-Henry was reported to have already organized 18 cells of 25 members each for the coup, which was intended to take place when Germany landed in Britain.

A fellow conspirator, Samuel Darwin-Fox, told an MI5 agent that:"Italy would declare war almost immediately, that France would then give in and that Britain would follow before the end of the week.

There would be a short civil war, the Government would leave first for Bristol and then for the Colonies, General Ironside would become dictator and after things had settled down Germany could do as she liked with Britain.

They have been expressed in various ways, but Fuller's 1925 arrangement is as follows: Cabalistic influences on his theories can be shown by his use of the "Law of Threes" throughout his work.

[27] Fuller did not believe the Principles stood alone as is thought today,[28] but that they complemented and overlapped each other as part of a whole, forming the Law of Economy of Force.

[29] These Principles were further grouped into the categories of Control (command / co-operation), Pressure (attack / activity) and Resistance (protection / stability).

[30] These Principles of War have been adopted and further refined by the military forces of several nations, most notably within NATO, and continue to be applied widely to modern strategic thinking.

[34] The book was carefully read by General Heinz Guderian of later Blitzkrieg fame and at the time Germany's foremost tank expert.

While serving in the First Oxfordshire Light Infantry he had entered and won a contest to write the best review of Crowley's poetic works, after which it turned out that he was the only entrant.

During this period he wrote The Treasure House of Images, edited early sections of Crowley's magical autobiography The Temple of Solomon the King and produced highly regarded paintings dealing with A∴A∴ teachings: these paintings have been used in recent years as the covers of the journal's revival, The Equinox, Volume IV.

Fuller, a man famous in arms and letters, one who has known the greatest statesmen, warriors, dictators, of our age, declare solemnly that the most extraordinary genius he ever knew was Crowley."
