Word in New: Red Line

The "line" part is easy to figure out. The "red" part is a little more mysterious.

Sometime in the next week or so the world will finally learn one way or the other what it means to cross a red line. A little over a year ago President Obama warned Syrian authorities that for them to use chemical weapons in their ongoing civil war would be to cross a red line. "That would change my calculus. That would change my equation," he said at the time.

Now the Syrian Army appears to have done precisely what he warned them not to do. According to the U.S. government's reckoning, some 1,429 people – including 426 children – were killed by deadly sarin gas during a rocket attack by the Syrian Army on August 21: a pretty specific crossing of the red line. As a result, red lines and the likely consequences of crossing them have been much in the news. Just this week, at a news conference in Stockholm, Obama declared: "I didn't set a red line. The world set a red line."


The phrase "red line" appears to be an adaptation of a much older metaphor—a "line drawn in the sand," according to Ben Yagoda, a professor of English and journalism at the University of Delaware. One of the earliest recorded instances of anyone drawing a line in the sand took place in ancient Rome around 168 B.C., during a conflict that, curiously enough, involved Syria. A Roman envoy named Popillius was sent to tell King Antiochus IV to abort his attack on Alexandria. When Antiochus tried to play for time, Popillius drew a line in the sand around him and told him he had to decide what he was going to do before he crossed it. He acceded to the Roman demands.

But just how the venerable line in the sand came to be red is a little unclear. One possibility is that a pundit borrowed the idea of the warning line on a gauge beyond which it is unsafe to rev up the machinery. Another explanation comes from the Battle of Balaclava on October 24, 1854, when the hopelessly outnumbered Sutherland Highlanders, the 93rd Highland Regiment, were told by their commander Sir Colin Campbell: "There is no retreat from here, men. You must die where you stand." And so they stood firm, wearing their scarlet tunics and awaiting the charge. In his breathless account of the battle, London Times correspondent William Russell wrote that all that remained between the charging Russians and the British regiment's base of operations was "a thin red streak tipped with steel."

Historic/Literary References

There are a couple of well-known early American references to the line in the sand. In Tom Sawyer (1876) Tom draws such a line with his big toe and dared another boy to cross it (spoiler alert: he did). Colonel William Travis drew a fateful line in the sand at the Alamo in 1836, asking volunteers to cross the line and join him in remaining to fight despite hopeless odds.

The courage and steadfastness of the "thin red line" at Balaclava in staying the course was celebrated by poets from Tennyson ("The Charge of the Light Brigade") to Kipling ("Tommy") and over time became a metaphor for steely resolve and a firm stance.

In a lighthearted vein the metaphor shows up in Carry On … Up the Khyber (1968), a British comedy set in the days of the British Raj, when Private Jimmy Widdle, fearing an attack, paints a red line on the ground and declares, "They'll never get past this."

Current Usage

In the modern-day political arena, Yagoda has found uses dating back to 1987, with references to "red lines" in conflicts between Chad and Libya, and in a 1999 article in the New York Times that reported that Muslim clerics in Iran had set out a "red line for the revolution" that no one should cross.
