On May 4, the English force eventually arrived at Corunna where the lower town was captured and plundered, and a number of merchant ships were seized. Norreys then won a modest victory over a Spanish relief militia force at Puente del Burgo. When the English pressed the attack on the citadel, however, they were repulsed. In addition, a number of English ships were captured by Spanish naval forces. With the failure to capture Corunna the English departed and headed towards Lisbon, but owing to poor organisation and lack of co-ordination (they had very few siege guns) the invading force also failed to take Lisbon. The expected uprising by the Portuguese loyal to Crato never materialised. With Portuguese and Spanish reinforcements arriving the English retreated and headed North where Drake sacked and burned Vigo. Sickness then struck the expedition, and finally, a portion of the fleet led by Drake headed towards the Azores, which was then scattered in a storm. Drake then took the best part of the fleet and plundered Porto Santo in Madeira before they limped back to Plymouth.
