Britain was worried about Spain's rule over the sea and New World so England had Sea Dogs attack Spanish boats. Spain didn't like this so they took their whole armada to an English harbor. Spain was expected to crush England, but against all odds, England won. They had fast boats compared to Spain's giant boats. Luckily for the English, as Spain was regathering, a storm came and destroyed the rest of the boats from the first attack. This defeat led to England becoming a much bigger power of the sea and opening trade for other countries.
