On July 26, 1956, Egypt made the decision to nationalize the Suez Canal. France and England who are the owners send their military troops who land at Fort-Fouad and Port Said on November 5 and 6, 1956. But at the threat of Soviet intervention and under the joint pressure of the United States, the French and British paratroopers must stop firing only a few hours after defeating the Egyptian troops. The intervention ends November 6, 1956 at midnight ... leaving room for UN troops arriving on the spot on November 15. This fiasco will spell the end of French and British influence in the Middle East and the end of the colonial era. It is on the occasion of this expedition that will be "modified" the notes of 50, 100 and 1000 francs from the issue of the "French Treasury". The three banknotes are identical to two black surcharges intended to obscure the words "Territoires occupés" and "ce billet à cours uniquement dans les territoires occupés", and a statement printed in black capitals at the bottom of the notes: "Forces Françaises en Méditerranée Orientale".
