The Combined Chiefs of Staff authorised Morgan to issue orders in the name of the Supreme Allied Commander to the Commanders in Chief of the Air, Naval and Land Forces, even though they outranked him. When Montgomery was appointed Commander in Chief Land Forces for the invasion, in December 1943, he declared that Morgan's original plans were unworkable; they had originally been limited by the availability of landing craft, but Montgomery insisted it would require more men attacking over a wider front. Ultimately, more landing craft were obtained and the invasion was scaled up to Montgomery's satisfaction, at the cost of a month's delay and a reduction in the Southern France operation

 but declined in favour of becoming one of Smith's three deputies. His responsibilities covered Intelligence and Operations. Morgan coordinated the work of various SHAEF divisions and deputised for Bedell Smith when he was absent.

Morgan also was called upon on occasion to deal with Montgomery, with whom his professional relationship as Deputy Chief of Staff was similar to that before the war when Montgomery was a brigade commander. On one occasion Morgan was summoned to Smith's office to find him white with rage at a telephone receiver. "That's your bloody marshal on the other end of that," Smith explained. "I can't talk to him any more. Now you go on." "As the campaign progressed," Morgan late wrote, "it became more difficult for us British at SHAEF to provide explanation, as we were continually called upon to do, for the attitude and behaviour of the British authorities as exemplified by their chosen representative in the field."

 and Jock Whiteley remained loyal to Eisenhower. This cast a pall over their careers after the war, when Montgomery became Chief of the Imperial General Staff.

After the war Smith described Morgan as his British alter ego, "a man I wouldn't willingly have dispensed with." Morgan served in this role until SHAEF was dissolved in June 1945.

 (UNRRA) in Germany. He applied his energy and planning skills to the problem of providing relief to millions of refugees and displaced persons in Europe in the wake of the war. However he became frustrated with the inefficiency of the United Nations organisation, and events in the British–Zionist conflict in the British Mandate for Palestine made him feel conflicted betweens his role in assisting Jewish refugees at UNRRA, whom he regarded as special victims of the Nazis for being persecuted solely for their race, and supporting British policy as a British Army officer. In January 1946 he created a furore by claiming at a press conference that there was a secret Zionist organisation that was attempting to facilitate an "exodus" of Jewish people from Europe to a new state in Palestine with Soviet encouragement. He later wrote:

A correspondent reported that Morgan made "casual observations based on what he saw... but the controversial remarks were taken out of the context and put together by correspondents." UNRRA expected that Morgan would offer his resignation but he did not do so. An attempt to clarify his position "off the record" failed, and Morgan's position in Germany was eliminated by UNRRA Director Fiorello La Guardia.

Morgan's statements caused a furor in the press, which portrayed them as antisemitic and distasteful. However, Morgan's comments were factual, based on military intelligence. It was reported at the time in Time magazine that: "Observers here [in Berlin]... are positive of [Morgan's] sincerity, and know he had no intention of feeding the fires of anti-Semitic propaganda."

In a world as closely integrated as this one is, the question must be asked: what is the standard of truth in journalism? When the journalist is dealing with an inflammatory subject and so reports it that verbally his story is true, but the overall effect is false, are the standards of truth satisfied?"

Morgan, coming from his military background, was appalled at the corruption, inefficiency and political diversion of UNRRA. A member of his staff said that "to serve such an outfit is degradation beyond description. In fact, [Morgan wrote], to have been rejected for such service I have always felt to have been a high honour."
