The ensign of the United States refers to the flag of the United States when used as a maritime flag to indentify nationality. As required on entering port, a vessel would fly her own ensign at the stern, but a conventional  token of respect to the host country would be to fly the flag of the host country (the United States in Boston Harbor, for example) at the foremast. See The "Britannia" Entering Boston Harbor, 1848 (inv. 49) for an example of a ship doing this. The American ensign often had the stars in the canton arranged in a circle with one large star in the center; an alternative on merchant ensigns was star-shaped constellation. In times of distress a ship would fly the ensign upside down, as can be seen in Wreck of the Roma, 1846 (inv. 250).

 The use of flags on vessels is different from the use of flags on land. The importance and history of the flagpole in Fresh Water Cove in Gloucester is still being studied.

The modern meaning of the flag was forged in December 1860, when Major Robert Anderson moved the U.S. garrison from Fort Moultrie to Fort Sumter in Charleston Harbor. Adam Goodheart argues this was the opening move of the American Civil War, and the flag was used throughout northern states to symbolize American nationalism and rejection of secessionism.

Before that day, the flag had served mostly as a military ensign or a convenient marking of American territory, flown from forts, embassies, and ships, and displayed on special occasions like American Independence day. But in the weeks after Major Anderson's surprising stand, it became something different. Suddenly the Stars and Stripes flew—as it does today, and especially as it did after the September 11 attacks in 2001—from houses, from storefronts, from churches; above the village greens and college quads. For the first time American flags were mass-produced rather than individually stitched and even so, manufacturers could not keep up with demand. As the long winter of 1861 turned into spring, that old flag meant something new. The abstraction of the Union cause was transfigured into a physical thing: strips of cloth that millions of people would fight for, and many thousands die for.

The use of signal flags, for ship-to-ship communication, generally preceded land-based chains of maritime semaphore stations, the latter using flags or rotating arms, until the advent of the electric or magnetic telegraph.

Until the end of the Napoleonic wars, merchant ships generally sailed in convoy as ordered by the escorting warship(s) using a few simple flags. Peace brought independent voyaging, the end of the convoy system, and the realization by various authorities that merchant vessels now needed their own separate means of signaling to each other. This resulted in a handful of rival codes, each with its individual flags and syntax. In general, they each had a section enabling ship identification and also a "vocabulary" section for transmitting selected messages. It was not until 1857 that a common Commercial Code became available for international use, only gradually replacing the earlier ones. All existed side by side for a decade or two.

Signal systems for American ships were originally intended to identify a vessel by name and owner; only later were more advanced systems developed to convey messages. Most basic were private signals, or "house flags", each of a different design or pattern, identifying the vessel's owner; identification charts were local and poorly distributed, limiting their usefulness. A secondary signal, a flag or large pennant bearing the vessel's name, was sometimes flown by larger ships, but pictorial records of them are uncommon. These private signal flags usually flew from the foremasthead or main masthead if a three master ship. Pilot boats had their own identifying flags, blue and white as seen in Spitfire Entering Boston Harbor, n.d. (inv. 536). Small vessels, such as schooners, often had a "tell-tale" pennant, an often-unmarked and often red flag, that was used to determine wind direction.

A numerical code flag system, identifying vessels by the code numbers, was introduced by Captain Frederick Marryat R.N. in 1817 for English vessels. American vessels soon adopted this system. Elford's "marine telegraphic system" was the first American equivalent to the Marryat code flags, first issued in 1823, and with changes, remaining in use until the late 1850s. Most of the signal flags on vessels depicted by Lane use Elford's; Brig "Antelope" in Boston Harbor, 1863 (inv. 43) is a noteworthy example of his depiction of Marryat's. The Elford's Code was popular in America on account of its simplicity and only required six blue and white flags. Eventually these changed to red and white, although it is unclear exactly when this happened. Instructions and a key ot the Elford's Code's use are included in successive editions of the Boston Harbor Signal Book.

Whereas the other codes employ at least ten flags of diverse shapes and colours, there are only six Elford flags in total, representing the numbers one to six. All are uniformly rectangular and monochrome in colour (either blue and white or red and white—or even black and white as in an early photograph). Selected from these six flags each individual vessel is allotted a combination of four flags to be prominently displayed as a vertical hoist. Reading from above down these convey its "designated number." Armed with this number and the type of vessel (e.g. ship, bark, brig, schooner /or steamer) the subject can be uniquely identified by reference to a copy of the Boston Harbor Signal Book for the appropriate year.
