Resistance to colonial rule is a dominant topic in the historical study of Africa. But resistance to attempted transfer of colonised peoples and territories, to promote peace in Europe, has not gained similar attention in African and colonial historiographies. This article looks at how rumours and reports of Nazi Germany's colonial demands in Africa, and the ambiguous reactions of British officials to them, shaped conversations among colonised peoples about their dignity under British colonialism and in intra-European diplomacy. The article argues that the prospect of Nazi rule and its spectre of slave-labour concentration camps for Africa's Western-educated elites, and other colonial subjects, bound these segments of colonial society closer to British, and French, imperialism than they relished at an uncertain, but critical moment in African and international history. They became the defenders of colonial systems they deplored, and opponents of a ruthless regime they feared.
