Waiting off Calais for an army that could not come
By August 1588 the Armada lay anchored off Calais, waiting to make contact with the Duke of Parma's army. Parma could not reach it: Dutch vessels under Justin of Nassau were blockading the Flemish ports.
Long-range English cannon fire had achieved little against the tightly packed anchorage. On 7 August Lord Howard of Effingham decided to use fireships instead. English documents, still Julian, date that night 28 July.
Midnight
At about midnight the English released eight burning vessels toward the Spanish anchorage. The English fleet stationed there numbered about 136 vessels after Seymour's reinforcement.
Rather than risk the flames, Spanish captains severed their anchor cables. The Armada's close defensive formation came apart in the dark.
What the burning ships actually did
The fireships mattered for the panic, the severed anchors, and the broken formation — not because they burned a large number of Spanish warships.
Driven north in a straggling line, the Spanish ships moved off the Flanders coast, and the English pursued and attacked them at Gravelines the following day.
Because the operation ran across the night of 7–8 August New Style, accounts attach it to either calendar day; the battle itself belongs to 8 August.

Traditional date. This date is the conventional one, not one fixed by a contemporary record.
What the sources leave uncertain
- The fireship attack occurred around midnight on the night of 7–8 August New Style, so accounts may attach it to either calendar day.
- English contemporary documents used the Julian calendar, ten days behind the Gregorian calendar used by Spain. The corresponding English Old Style date was 28 July.
- The Battle of Gravelines itself belongs to 8 August New Style, not 7 August.
