Jay Burleson, Flash in the Pan, 1756 French Infantry
Musket Demonstration, Fort Ticonderoga, New York

This photograph is, for several reasons, one of my favorites. Taken in 2015 with a Leica M9 and 75mm ƒ/2, the exposure, composition, and timing were all done well; the subjects are isolated from the background; and all three reenactors express varied and intriguing facial expressions. Most of all, you are seeing a demonstration of an extremely geeky process, frozen in the midst of happening—the firing of a flintlock musket. (Yes, referencing the recent TOP article, firearms aficionados also fit the definition of "geeks." Often right out to the extreme edge of the bell curve.)

The firearms pictured are modern reproductions of the French Charleville musket, first manufactured in 1717. Its production ended sometime during the 1840s. It was a .69 caliber smoothbore flintlock muzzle-loading musket used by French infantry forces around the world, including in many battles at and around Fort Ticonderoga in the mid-18th century. The flintlock mechanism was developed in the early 16th century and was pretty much the standard for firearms until the early 19th century.

The basic working of a flintlock is simple: the hammer, under spring tension, is holding a piece of flint, and when the trigger is pulled, the flint pivots forward forcefully and scrapes the flint against the frizzen or steel, resulting in a shower of sparks that ignites a small amount of black powder in the pan. From an engineering standpoint, the entire system is elegant in its robustness and simplicity.

When the black powder in the pan is ignited, some of the flame created by the burning powder enters a small hole, called the touch hole, drilled through the side of the barrel into the barrel's chamber, which subsequently ignites the main charge of powder in the barrel. The lead-ball projectile, which is seated into the barrel on top of the black powder, is then propelled out of the barrel.

If, under the stress of reloading your musket in a life-or-death situation, you forget to put a charge of black powder in the barrel, the flame from the pan has nothing to ignite, hence it's just a "flash in the pan." Most reference authorities agree that this—as illustrated in the photograph—is the origin of that phrase "flash in the pan," meaning "something which disappoints by failing to deliver anything of value, despite a showy beginning."

Despite my title, I do like to think that this photograph does deliver something of value, after its showy beginning!

Keith: "An interesting side note regarding flintlocks; unlike the primer-based ignition in modern firearms, there is a noticeable delay between pulling the trigger and the actual firing of the gun, requiring a 'follow through' of maintaining the sights on target for an additional second after pulling the trigger. Failure to do so would yield a shot way off target. This delay earned the mechanism the alternative name of 'flinchlock,' because any flinching by the shooter is greatly exaggerated by the delay."

David Dyer-Bennet: "Very nice! Getting the priming charge so clearly is fairly rare."
