"In the course of the Casablanca Conference, General de Gaulle, who was in London, had been invited by the Prime Minister to come to North Africa. De Gaulle was offended that he had not been invited further in advance, and in one way and another proved to be his usual difficult self. Mr. Eden, the Foreign Secretary, had to exert great pressure to induce him to leave London for Casablanca. When he arrived there the firmest treatment by Mr. Churchill was required to persuade him to call upon Giraud. Finally in the interests of at least good public feeling a "shot-gun marriage" was arranged. At a press conference on 24 January, De Gaulle and Giraud were made to sit in a row of chairs, alternating with Mr. Roosevelt and Mr. Churchill, and to be photographed shaking hands. As the newsreel cameras finished their work, each French general dropped the other's hand as though it were red hot. At the press conference following this remarkable photograph, the President first made publicly the often-quoted statement concerning "unconditional surrender." As the war continued, King became more and more convinced that this favorite slogan was a mistaken one. Slogans are popular in the United States; they are terse and sometimes they fit the situation. Like newspaper headlines, however, they are unduly rigid, and always discourage thought. King would have preferred to have had this one left unsaid."
