The British Government decided to undertake massive fortifications in the 19th century and to create a strategic harbour to deter attacks from France. These fortifications were presciently described by William Ewart Gladstone as "a monument of human folly, useless to us ... but perhaps not absolutely useless to a possible enemy, with whom we may at some period have to deal and who may possibly be able to extract some profit in the way of shelter and accommodation from the ruins." An influx of English and Irish labourers, plus the sizeable British garrison stationed in the island, led to rapid Anglicisation. The harbour was never completed – the remaining breakwater (designed by James Walker) is one of the island's landmarks, and is longer than any breakwater in the UK.
