It's the birthday of the US Navy

On 13 October 1775, the Continental Congress, meeting in Philadelphia, authorized the procurement, fitting out, manning, and dispatch of two armed vessels to cruise off our coasts to interdict British supply ships.

The beginning of the Navy hymn:

Eternal father, strong to save,

Whose arm hath bound the restless wave,

Who bidd'st the mighty ocean deep

Its own appointed limits keep;

O hear us when we cry to thee,

For those in peril on the sea.
