Grand Armada

The Spanish Armada. A massive fleet that England could not defeat, and the only hope for them was pure luck. In OTL, the English were lucky. The waters near Britain were rocky and forced the Spaniards to scuttle their ships. It was the water that kept the English from falling to the Spanish and losing their destiny as the British Empire. However, it is not hard to imagine another situation in which a Spanish victory may occur.

Don Alonso, leader of the Spanish Armada, launched a planned invasion of England in 1588. Several sailors saw that the waters around England were extremely turbulent. Alonso knew about Julius Caesar's failed invasion of Britain and did not want his fleet to suffer the same fate as Caesar. Alonso ordered the turning back of the Spanish Armada back to Spain. This move led to the stripping of Alonso's titles and his imprisonment. However, a much more capable man, Don Jerónimo de Carranza, was made commander-in-chief of the Spanish Armada and, the following year, the Spanish Armada, this time resupplied and ready to destroy England, invaded England. The fleet came up the River Thames, striking fear in the British populace. Windsor Castle was shelled by the Armada and the entirety of the English royal family except for Queen Elizabeth was killed. Queen Elizabeth was forced to give reign over England to King Philip II. Philip II was king of Spain, Portugal, the Spanish Netherlands, Naples, and England. The English Inquisition was made to root out Protestantism while large numbers of English refugees fled to Scotland.
