“Ye mariners of England,
That guard our native seas;
Whose flag has braved, a thousand years,
The battle and the breeze!”

Old England is our Home, reported in Bartlett's Familiar Quotations, 10th ed. (1919).

"The Dirge of the Sea" (April 1891)
Context: Years! Years, ye shall mix with me!
Ye shall grow a part
Of the laughing Sea;
Of the moaning heart
Of the glittered wave
Of the sun-gleam's dart
In the ocean-grave. Fair, cold, and faithless wert thou, my own!
For that I love
Thy heart of stone!
From the heights above
To the depths below,
Where dread things move, There is naught can show
A life so trustless! Proud be thy crown!
Ruthless, like none, save the Sea, alone!

Boston Massacre Oration (1774)
Context: A well-disciplined militia is a safe, an honorable guard to a community like this, whose inhabitants are by nature brave, and are laudably tenacious of that freedom in which they were born. From a well-regulated militia we have nothing to fear; their interest is the same with that of the State. When a country is invaded, the militia are ready to appear in its defense; they march into the field with that fortitude which a consciousness of the justice of their cause inspires; they do not jeopard their lives for a master who considers them only as the instruments of his ambition, and whom they regard only as the daily dispenser of the scanty pittance of bread and water. No; they fight for their houses, their lands, for their wives, their children; for all who claim the tenderest names, and are held dearest in their hearts; they fight pro aris et focis, for their liberty, and for themselves, and for their God.

Ye Gentlemen of England, (c. 1630), reported in Bartlett's Familiar Quotations, 10th ed. (1919).
