What year was the easter rising in ireland?

In an effort to thwart informers, and, indeed, the Volunteers' own leadership, early in April Pearse issued orders for 3 days of "parades and manoeuvres" by the Volunteers for Easter Sunday (which he had the authority to do, as Director of Organization). The idea was that the true republicans within the organization (particularly IRB members) would know exactly what this meant, while men such as MacNeill and the British authorities in Dublin Castle would take it at face value. However, MacNeill got wind of what was afoot and threatened to "do everything possible short of phoning Dublin Castle" to prevent the rising. Although he was briefly convinced to go along with some sort of action when MacDermott revealed to him that a shipment of German arms was about to land in County Kerry, planned by the IRB in conjunction with Sir Roger Casement (who ironically had just landed in Ireland in an effort to stop the rising), the following day MacNeill reverted to his original position when he found out that the ship carrying the arms had been scuttled. With the support of other leaders of like mind, notably Bulmer Hobson and The O'Rahilly, he issued a countermand to all Volunteers, canceling all actions for Sunday. This only succeeded in putting the rising off for a day, although it greatly reduced the number of men who turned out.
