Preparations made by Jean de Valette
1. Forts St Angelo, St Elmo and St Michael were strengthened, as were also defensive walls around the towns of Birgu and Senglea
2. An iron chain was placed under the surface of the water to deny the Turkish ships entry into the creek between the two towns of Birgu and Senglea
3. A pontoon bridge was constructed between Birgu and Senglea to be able to send reinforcements, weapons and provisions between these two towns
4. The Dejma militia was re-trained and all able-bodied Maltese men were trained in the use of arms, while those who were not fitted to fight, such as the old and the sick were transported to Sicily
5. De Valette asked the Christian rulers of Europe to send to Malta all that could spare for the siege against the Turks, such as soldiers, weapons, ammunition, food and medicines
6. Besides some 700 knights, the Order had around another 9,000 Maltese, Spanish, Italian and Sicilian soldiers to defend Malta against the Turks
