“the Ottoman Empire was an old American ally since the Revolution.”
Really, because your ignorance of history is showing again.
While there were Germans in America as colonists, the British enlisted the the Germans as mercenaries and were an item in the Declaration of Independence: “He is at this time transporting large Armies of foreign Mercenaries to compleat the works of death, desolation and tyranny, already begun with circumstances of Cruelty & perfidy scarcely paralleled in the most barbarous ages, and totally unworthy the Head of a civilized nation.”
Sorry but Germany wasn’t a friend during that time and they even refused to acknowledge America as a nation until 1783 when we signed the Treaty of Paris.
Germany in 1776 was, of course, non-existent. But the German speaking peoples were rather clustered in Central Europe and had a number of states.
