The number of “destitute negroes” had also increased by the end of the eighteenth century; in particular black recruits who had fought for the English during the American War of Independence fell into dereliction on their arrival. This was another aspect of immigration, where the influx was the direct result of the actions of the host country; in that sense these black ex-soldiers created a recognisable line of descent to those twentieth-century migrants who left the ruins of empire. A pamphlet issued in 1784 stated that thousands of blacks “traversed the town, naked, pennyless, and almost starving.” As a result they were believed to threaten social order. The African, Afro-American or West Indian-as long as his or her skin was of the appropriate hue-was always and instinctively considered a “threat.” With that fear came also the prospect of miscegenation, since mixed marriages were not unusual in the poorer areas of London. Here the sixteenth-century connection of the “Moor” with lasciviousness was once more revived, as if a black skin were a token of “black” desires lying just beneath the surface of the human order. “The lower classes of women in England are remarkably fond of the blacks,” it was reported, “for reasons too brutal to mention.” A Committee for Relieving the Black Poor was set up with the sole purpose of assisting in expatriation. It was not a success. Less than five hundred, out of a population estimated between 10,000 and 20,000, embarked upon the emigrant ships-an indication, perhaps, of the fact that London remained their chosen city. However dolorous or impoverished their lives, the majority of black immigrants wished to remain in a place which in its daily commerce remained one of opportunity and diversion.
That population became acclimatised and, although still subject to racial taunts, a familiar presence in the streets of nineteenth-century London. They had become part of the “underclass” and were scarcely to be differentiated from it; as crossing-sweepers, as vagrants, or as beggars, they had become almost invisible. In the vast city they did not exist in numbers large enough to command public attention or concern; they were not competing for employment and so did not threaten anyone’s livelihood. They rarely appear in novels or narratives, except as occasional grotesques, and their general fate seems to have been one of settlement among the urban poor.
Yet the beginning of immigration from the Caribbean islands in the late 1940s set off a litany of familiar fears, among them the prospect of white unemployment, of intermarriage, and of general overpopulation. In the summer of 1948 the SS
