Waking after a night at sea, I was elated to look out of the cabin window and see the city of Algiers, blazing white. The splendid capital rises from its Mediterranean bay in improbable layers, from the arches of the French colonial port to the warren of the Casbah, to the clear blue sky, all overlooked by the Martyrs’ Memorial, which represents the country’s fight for independence. “Never was town more nobly placed,” wrote Edith Wharton, who visited by yacht in 1888. In the cabin, my toddler son was still sleeping. I looked at him and thought, we’ve made it, baby: all the way from West Yorkshire to north Africa by rail and sea in 48 hours.
