On August 7 a joint attack was made on the land side of Senglea and on
the bastion of Castile. On that day the Turks came nearer success than
ever before or after. Mustapha's desperate attacks on Senglea were
at last successful: masters of the breach made by their guns, the
assailants' weight of numbers began to tell, and slowly the defenders
were being pushed back inside the fortress. At this moment, to
