In the wake of reorganising his navy,
King Philip II of Spain was intent on establishing advanced bases in western France from which his navy could constantly threaten England and Ireland. In 1593
Blavet had been established by the Spanish in Brittany and news of this caused concern in England. Reports of a Spanish expedition under
Juan del Águila hoping to seize the major port of Brest caused greater concern and
John Norreys, already in France, wrote a warning letter to the Queen. Elizabeth, seeing the danger, ordered Norreys to join with
Martin Frobisher and expel the Spanish. As part of Spanish preparations for an intended siege of Brest, a well-situated fort was to be built on the peninsula completely commanding the
Roadstead of Brest. Águila's chief engineer, Captain
Cristóbal de Rojas, designed a modern fortification, christened
El Leon - companies took turns in construction, foraging, and defence. Spanish admiral
Pedro de Zubiaur arrived with twelve ships landing equipment, which accelerated the construction of the fort, and two shaped
bastions with a
glacis were formed in front of the drawbridge guarding where the peninsula joined the mainland. The fort had a significant number of guns, one bastion containing eighteen
culverins and another smaller bastion had six; many of these guns were brought by the fleet of Zubiaur. Don
Tomé de Paredes was appointed commander of the garrison of the fort, with his company, that of Diego de Aller and Pedro Ortiz Dogaleño totalling 401 men, with a mission to complete the construction of the fort. In June, 1,000 veteran English troops led by Sir
Thomas Baskerville, who had been fighting in the Netherlands, were the first to arrive, landing at
Paimpol. This was joined in August by another force of 2,000 soldiers from
Plymouth under the command of John Norreys and ten ships of war with 1,200 sailors and marines commanded by Martin Frobisher in his flagship
Vanguard. The French under the overall command of Jean VI d'Aumont consisted of 3,000 troops, under the command of Baron de Molac, 300 mounted arquebusiers and 400
knights. In the opening campaign the town of
Morlaix was
besieged and captured from the Spanish and Leaguer forces in September. The town of
Quimper was taken next and in October the Anglo-French force headed towards Brest to lay siege to the Crozon peninsula. ==Siege==
