The ship upon which Ulloa was travelling was captured by the British, and he was taken as a prisoner to England.
His name is also recalled as the meterological term Ulloa's halo (also known as Bouguer's halo) which an observer may see infrequently in fog when sun breaks through (for example, on a mountain) and looks down-sun -- effectively a "fog-bow" (as opposed to a "rain-bow").
