In 1943, when Mass Observation studied the attitude of the British to their allies, it found that the Czechs and the Dutch were the most popular. Little was known about them, except that they were conducting a heroic resistance to Germany. The Free French were well regarded by about half the sample. The Poles, always rather controversial, had lost further popularity by the friction between their Government-in-exile and the Russians. The Americans were only slightly more popular; one-third of those questioned expressed a favourable opinion. After Mussolini's fall in the summer of that year, they were actually less well spoken of than the Italians.
