Principle perhaps was at stake; but the principle of the sanctity of international treaty, which brought Britain into the war, scarcely merited the p… - John Keegan

The system of communication itself denied any rapidity, let alone instantaneity, of communication when it was most needed, which was in the heat of action. The most important of the novelties of modern warfare in our own time has been the development of surveillance, targeting and inter-communication in real time, which is to say at the speed at which events unroll.

The tragedy of the diplomatic crisis that preceded the outbreak of the fighting in August 1914, which was to swell into the four-year tragedy of the Great War, is that events successively and progressively overwhelmed the capacity of statesmen and diplomats to control and contain them. Honourable and able men though they were, the servants of the chancelleries and foreign officers of the great powers in the July crisis were bound to the wheel of the written note, the encipherment routine, the telegraph schedule. The potentialities of the telephone, which might have cut across the barriers to communication, seem to have eluded their imaginative powers. The potentialities of radio, available but unused, evaded them altogether. In the event, the states of Europe proceeded, as if in a dead march and a dialogue of the deaf, to the destruction of their continent and its civilisation.

All European armies in 1904 had long-laid military plans, notable in most cases for their inflexibility. None was integrated with what today would be called a ‘national security policy’, made in conclave between politicians, diplomats, intelligence directors and service chiefs, and designed to serve a country’s vital interests, for such a concept of national leadership did not then exist. Military plans were held to be military secrets in the strictest sense, secret to the planners alone, scarcely communicable in peacetime to civilian heads of government, often not from one service to another.
