The city was witness to attacks from the English led by Sir Francis Drake in 1595 (in what is known as the Battle of Puerto Rico) and by George Clifford, Earl of Cumberland, in 1598. Artillery from San Juan's fort, El Morro, repelled Drake; however, Clifford managed to land troops and lay siege to the city. After a few months of English occupation, Clifford was forced to abandon the siege when his troops began to suffer from exhaustion and sickness. In 1625 the city was sacked by Dutch forces led by Captain Balduino Enrico (also known as Boudewijn Hendricksz/Bowdoin Henrick), but El Morro withstood the assault and was not taken. The Dutch were counterattacked by Captain Juan de Amézqueta and 50 members of the civilian militia on land and by the cannons of the Spanish troops in El Morro castle. The land battle left 60 Dutch soldiers dead and Enrico with a sword wound to his neck which he received from the hands of Amézqueta. The Dutch ships at sea were boarded by Puerto Ricans who defeated those aboard. After a long battle, the Spanish soldiers and volunteers of the city's militia were able to defend the city from the attack and save the island from an invasion. On October 21, Enrico set La Fortaleza and the city ablaze. Captains Amézqueta and Andrés Botello decided to put a stop to the destruction and led 200 men in an attack against the enemy's front and rear guard. They drove Enrico and his men from their trenches and into the ocean in their haste to reach their ships.leftThe British attack in 1797, during the French Revolutionary Wars, led by Sir Ralph Abercromby (who had just conquered Trinidad). His army laid siege to the city but was forced to withdraw in defeat as the Puerto Rican defenses proved more resilient than those of Trinidad. Various events and circumstances, including liberalized commerce with Spain, the opening of the island to immigrants as a direct result of the Royal Decree of Graces of 1815, and the colonial revolutions, led to an expansion of San Juan and other Puerto Rican settlements in the late 18th and early 19th century.
