One of the first times a black American flag entered the American consciousness was during the American Civil War of 1861 to 1865.
During that period, particular Army units flew the black flag to symbolize the opposite of the white flag of surrender. It means they would neither give, nor accept, quarter.
In other words, “no quarter will be given” means enemy combatants would rather be killed than taken prisoner.
The phrase “give no quarter” has origins as far back as the 17th century.
