The English, under the instructions of Lord Admiral Howard of
Efingham, deliberately sets fire to some of its ships and sends
them into the midst of the Spanish Armada, anchored off Calais.
This destroys many of the fleet's galleons, forcing them to abandon
their anchors and cast out to sea, losing their careful formation
in the process.
