Today is the Feast of the Holy Rosary
The feast commemorates the victory of the Christians over the Moslem's in the Battle of Lepanto. Interestingly, it is also the anniversary (1st) of the beginning of America's retaliation for the 9/11 terror attacks.
From the CATHOLIC ENCYCLOPEDIA: Feast of the Holy Rosary
More particularly, the naval victory of Lepanto gained by Don John of Austria over the Turkish fleet on the first Sunday of October in 1571 responded wonderfully to the processions made at Rome on that same day by the members of the Rosary confraternity.
