Emerald Peril
Ever since it was clear to the world that the war wouldn't end quickly, Britain had worried about its unruly member of the UK, Ireland. Since the Acts of Union unified Great Britain & Ireland in 1801 London had had a problem with the islands populace. Twice, once in 1848 & again in 1866, the Irish had rebelled against British rule only to be put down. Now that Britain was stuck in a devastating was around the world their were fears that Germany or the US would try & stir up the Irish into rebelling once more. In this area Britain was correct, almost as soon a the war began American & German agents in Ireland began working with working with the nationalists their to stir the country into rebellion. By 1913 Irish nationalists had been planning an uprising for three years. Also for nearly two years American & German warships had been smuggling weapons into Ireland whenever possible to give the uprising a fighting chance of survival.
On March 23, Easter Sunday, the first rays of sunlight began to show themselves across Ireland in what looked to be a peaceful day. Along the western coast of the island however several dozen gray shapes were appearing. The shapes quickly took the form of two dozen American & German warships supporting a fleet of cargo & transport vessels. Within minutes the waters of the Shannon Estuary were filled with both landing craft & regular small boats landing 15,000 US Marines & several tons of equipment & supplies. War had now arrived in the British Isles but the landing was only a small part of it & was used as a signal seen across Ireland. At 1300 all across Ireland, but mostly focused in Cork, Dublin, & Belfast, close to 50,000 Irish nationalists rose up in rebellion. The Easter Uprising had began.
Britain had already heard of the American invasion force & had quickly mobilized most of the division stationed in Ireland & was moving to engage the Marines while Royal Navy units from Berehaven were sailing to engage the Allied fleet. The rebellion however, which deliberately several hours after the beginning of the American landings to catch the British on the move, quickly disrupted Britain's troop movements. At sea the RN sent a fleet of 5 pre-vengeance battleships, 8 cruisers, & 10 destroyers to intercept the Allies & destroy the invasion force before it had time to complete. However as the fleet neared the Dingle Peninsula it ran into an ambush staged by 15 German submarines. In minutes the submarines had sunk a battleship & 3 destroyers while another battleship & 2 cruisers were forced to withdraw. The remaining ships were then pounced on by US & German warships from the invasion fleet & within 2 hours the Battle of Dingle was over with only a damaged battleship, 3 cruisers, & 4 destroyers withdrew.
Within two days Cork, Dublin, & Belfast were under Irish control as well as several dozen more towns & smaller cities throughout Ireland & at Shannon Estuary 15,000 American Marines, 500 German Naval Infantry, & 5000 ethnic Irishmen of the American formed & trained Irish Home Army with an additional 20,000 rifles, 400 machine guns, 100 mortars, & 5 million rounds of ammunition for the Irish rebels had been offloaded. Over the next week the American led Expeditionary Force expanded their foothold capturing Limerick while only encountering light resistance. On April 2 they met up with the Irish Nationalists & began to form a join plan for operations against the British in Ireland. Not all was going well however, though thousands of rifles & hundreds of machine guns had been smuggled to the Irish one thing they didn't have however was artillery. By the first of April the British in Ireland had regrouped &, with some Royal Navy help, would retake Belfast & Dublin after bloody house to house fights. Two fresh divisions from Britain were now being sent to Ireland instead of France, And at sea the British Home Fleet rallied & drove the German & American warships from Irish waters. The Expeditionary Force was now unable to easily get reinforcements & the British felt that soon this uprising & invasion would be finished.
What Britain didn't know however, was that while the Easter Uprising was beginning in Ireland, a thousand miles to the north a massive American armada of warships & transports were sailing near Iceland carrying two divisions of American troops & supplies destined for Narvik. The warships guarding this convoy were to stay in European waters at Sweden while the convoy would hopefully return with more & more troops to assist the US's allies in Europe.
