Castle Bravo
Castle Bravo was the first in a series of high-yield thermonuclear weapon design tests conducted by the United States at Bikini Atoll, Marshall Islands, as part of "Operation Castle". Detonated on March 1, 1954, the device was the most powerful nuclear device detonated by the United States and its first lithium deuteride fueled thermonuclear weapon. Castle Bravo's yield was 15 megatons of TNT, 2.5 times the predicted 6.0 megatons, due to unforeseen additional reactions involving Li, which led to the unexpected radioactive contamination of areas to the east of Bikini Atoll.
Siege of Castelnuovo
The siege of Castelnuovo ended the failed campaign of the Holy League against the power of the Ottoman Empire in the Eastern Mediterranean. Charles V began negotiations with Barbarossa to attract him to the imperial ranks but in vain, and turned all his efforts in a great expedition against Algiers to destroy the Ottoman sea power. This expedition, known as the Journey of Algiers, ended in a disaster as a storm scattered the fleet and the army had to be reembarked having suffered heavy losses. A truce between Charles V and Suleiman the Magnificent was signed in 1543. Castelnuovo remained in Ottoman hands for almost 150 years. It was recovered in 1687, during the Morean War, by the Venetian Captain-General at sea Girolamo Cornaro, who in alliance with Montenegrins under Vuceta Bogdanovic, won a great victory over the Turks near the town and put the fortress under Venetian rule.
