The English sent in fireships , so the Armada cut their anchors to escape. On 28 July, the English attacked the Spanish fleet at the Battle of Gravelines. The English ships were easier to manoeuvre in the heavy waters of the North Sea. This decisive battle prevented the Spanish from landing in England. The most important reason the Spanish Armada failed was because the English had better leadership than the Spanish. Moreover, when Medina Sidonia had a chance to attack the trapped English fleet at Plymouth Harbour, he instead sailed past. As a result, he missed an opportunity to easily defeat the English fleet.As as well as food supplies being poor, the quality of weapons being used were also poor. In addition to this, the Spanish also suffered from poor communication between Spanish commanders and poor planning in the run up to the Armada.
