The Belfast Blitz consisted of four German air raids on strategic targets in the city of Belfast in Northern Ireland, in April and May 1941 during World War II, causing high casualties. The first was on the night of 78 April 1941, a small attack which probably took place only to test Belfast's defences. The next took place on Easter Tuesday, 15 April 1941, when 200 Luftwaffe bombers attacked military and manufacturing targets in the city of Belfast. Some 900 people died as a result of the bombing and 1,500 were injured. High explosive bombs predominated in this raid. Apart from those on London, this was the greatest loss of life in any night raid during the Blitz. The third raid on Belfast took place over the evening and morning of 45 May 1941; 150 were killed. Incendiary bombs predominated in this raid. The fourth and final Belfast raid took place on the following night, 56 May. In total over 1,300 houses were demolished, some 5,000 badly damaged, nearly 30,000 slightly damaged while 20,000 required "first aid repairs". Background As the UK was preparing for the conflict, the factories and shipyards of Belfast were gearing up. Belfast made a considerable contribution towards the Allied war effort, producing many naval ships, aircraft and munitions; therefore, the city was deemed a suitable bombing target by the Luftwaffe. Unlike N Ireland, the Irish Free State was no longer part of the UK. Under the leadership of Éamon de Valera it had declared its neutrality during the Second World War. Although it arrested German spies that its police and military intelligence services caught, the state never broke off diplomatic relations with Axis nations: the German Legation in Dublin remained open throughout the war. Government The Government of Northern Ireland lacked the will, energy and capacity to cope with a major crisis when it came. James Craig, Lord Craigavon, had been Prime Minister of Northern Ireland since its inception in 1921 up until his death in 1940. His death (along with preceding ill-health) came at a bad time and arguably inadvertently caused a leadership vacuum. Richard Dawson Bates was the Home Affairs Minister. Sir Basil Brooke, the Minister of Agriculture, was the only active minister. He successfully busied himself with the task of making Northern Ireland a major supplier of food to Britain in her time of need. John Clarke MacDermott, the Minister of Public
