Definition of "armistice"

135. An armistice is the cessation of active hostilities for a period agreed upon between belligerents.

It has also become routine to interrupt wars in more lasting fashion by imposing armistices. Again, unless directly followed by successful peace negotiations, armistices perpetuate the state of war indefinitely because they shield the weaker side from the consequences of refusing the concessions needed for peace. […] Armistices in themselves are not way stations to peace but rather frozen wars.

The government of Great-Britain lost no time after the war was known, in making to our cabinet proposals for an armistice. Those proposals were like all propositions between equal states, perfectly reciprocal. They require of us to suspend hostilities only, in consideration of suspending hostilities on their part. They are silent as to impressments—and would any person inquire why? It may be answered, that impressments had never been presented to Great-Britain as in themselves the cause of war— […]

The day armistice was signed [chapter title] […] At five o'clock on the morning of 11 November 1918, a group of high-ranking German politicians and military officers entered a railway carriage in the Forest of Compiègne. They were met by delegates from the countries with which they had been at war. Three days earlier the French, British and Americans had prepared an armistice document which they demanded the Germans accept within three days. Inside the carriage the Germans signed the surrender document put before them. The document signalled that the war would stop in six hours' time, at the eleventh hour of the eleventh day of the eleventh month of 1918.

The armistice of November 1918 could represent many things: the end of the war, the victory. But for the Carnard [the newspaper Le Canard enchaîné], first and foremost, it represented dissention among the French. […] After the armistice and the emergence of the first difficulties of the peace, many more both on the right and in the center argued that the armistice should have been signed in Berlin—in a word, the armistice of November 11 was premature.
