What does the Expression "Shot Across the Bow" Mean?

A Kaminsky
A Kaminsky

Expressions in the English language come from varied sources, such as foreign languages. Another popular source of colorful expressions is the military. Sayings like “dogfight,” “GI,” “SOP” and “snafu” all come from the military. One popular nautical term is “shot across the bow.” Like many expressions, it has a military, literal definition, as well as a figurative one.

In the days before radar, radio and high-powered binoculars, one ship meeting another at a distance might not be able to tell the country from whence she hailed. Therefore, in the 18th century, the captain would order a “shot across the bow,” that is, a harmless cannonball lobbed across the bow of the ship. This was essentially a way to hail the ship and ask her to show her colors. If the colors were of an enemy country, the captain might then order an attack on the ship, but the initial shot had to be made first for it to be a legitimate engagement.

The shot across the bow continued on into modern times, although usually, it is only used after the firing ship has unsuccessfully attempted to communicate via radio. This may happen when a ship strays from international waters or shows aggression. It may more accurately be called a warning shot nowadays, since the location of the shot is not always the same.

Sometimes, a fighter plane escort will fire the warning shots, which may be at a ship or at another plane in the wrong place. In almost all instances now, the shot across the bow is preceded by attempts at radio communication and negotiation. The shot says, “We’re serious. We will shoot to kill.”

The phrase also has a figurative definition. It usually refers to an action taken to show that someone is serious. For instance, someone may threaten a lawsuit, and a letter from the person’s attorney asking for a meeting or resolution of the problem is considered a shot across the bow. It is the deed that shows intent to act in a certain way. A negative campaign commercial against an opponent might also be considered such a warning shot, as it shows serious intent.

I find it disturbing how many negative campaign ads there are on TV lately. I would prefer a candidate who is able to be more secure about themselves and not feel like they always need to be attacking with shots across the bow. I think that in the long run, it is a very negative and harmful strategy.


A shot across the bow is an important technique for demonstrating that you are not to be messed with. In business and politics, it is necessary to be sure that you are staying on the offensive, rather than the defensive, to indicate a desire to compete and dominate. There are only victims and victimizers in this kind of a game, and campaigners know that they must demonstrate their seriousness with shots across the bow.
