On April 24, 1943 a fire started in the engine room of the Panamanian freighter SS El Estero. Fire can always represent a danger to a ship, but this fire offered particular concern. The El Estro was carrying more than thirteen hundred tons of high explosives, and was in New York Harbor.
The Reconquista, or Christian reconquest of Iberia, took nearly 800 years. The fighting did not come without great attempts by Muslim powers across the strait trying to reestablish their presence in mainland Europe. The last gasp of that effort came in the 1330s, when the powerful Marinid sultanate of what is modern Morocco invaded in an attempt to reverse Christian gains and secure the perilous position of the Sultanate of Granada.
