* 1309-While the King Ferdinand IV of Castile laid siege on Algeciras, Alonso Pérez de Guzmán ( known to the Spanish records as Guzmán el Bueno ) was sent to capture the town.

This was the First Siege of Gibraltar.

The Castilians took the Upper Rock from where the town was bombarded.

The garrison surrendered after one month.

Gibraltar then had about 1, 500 inhabitants.
