Elizabeth  I retaliated by supporting a Dutch revolt against Spain and funding attacks on Spanish ships.Though neither country officially declared war, this intermittent conflict between England and Spain began in 1585 with the former’s expedition to the Netherlands to support the Dutch revolt and continued for nearly two decades.The British sent eight fire ships toward the Armada, causing the Spaniards to worry about their wooden vessels. 
The August 8th battle of Gravelines was so fierce that both sides effectively exhausted their ammunition. For much of the battle, like much of the entire campaign, the Spanish were fighting both the British and the wind (which appeared to be pushing Spanish ships into the shoals.Then, the wind shifted. Philip's ships  were able to escape into the North Sea. Although battered, the Armada was effectively undefeated. Bloodied, the Spaniards were unbowed. 
In 1588, King Philip II of Spain sent an armada (a fleet of ships) to collect his army from the Netherlands, where they were fighting, and take them to invade England. This was done in the name of religion, because England had become Protestant and no longer accepted the Pope as the head of the Church; Spain was Catholic and the Pope had encouraged Philip to try to make England become Catholic again. He also had a political reason to go to war with England because Spain ruled the Netherlands, but the people there were rebelling against Spanish control and England had been helping them.
