Those who were in Dublin on Easter Monday 1916 were privileged to witness a scene which for dramatic setting and for paradoxical conception is certainly the most extraordinary of any of the long line of rebellions in Irish history, for at a time when it seemed almost universally admitted that Separatism was from an economic, racial, and military point of view utterly impossible, there suddenly arose without warning, without apparent reason, and as if from nowhere, a body of men, fully armed and completely organized, who within the space of a single hour had captured every strategic point in the capital, and to its utter amazement held it up in the name of a new Republic, in much the same way as a highwayman of old used to hold up coaches on Hounslow Heath.
