1844 CE

Samuel Colt had not refrained long from manufacturing, and turned to selling underwater electrical detonators and waterproof cable of his own invention.

Soon after the failure of the Patent Arms Manufacturing Company, he teamd up with Samuel Morse to lobby the U.S. government for funds.

Colt's waterproof cable, made from tar-coated copper, will prove valuable when Morse runs telegraph lines under lakes, rivers, bays, and in his attempts to lay a telegraph line under the Atlantic Ocean.

Morse will use the battery from one of Colt's mines to transmit a telegraph message from Manhattan to Governors Island when his own battery is too weak to send the signal.

When tensions with Great Britain prompted Congress to appropriate funds for Colt's project toward the end of 1841, he demonstrated his underwater mines to the US government.

In 1842 he had used one of the devices to destroy a moving vessel to the satisfaction of the United States Navy and President John Tyler.

However, opposition from John Quincy Adams, who was serving as a U.S. Representative from Massachusetts's 8th congressional district, scuttled the project as "not fair and honest warfare" and called the Colt mine an "unchristian contraption".

After this setback, Colt had turned his attention to perfecting tinfoil cartridges he had originally designed for use in his revolvers.

The standard at this time was to have powder and ball contained in a paper or skin envelope or "cartridge" for ease of loading.

However, if the paper gets wet it will ruin the powder

Colt had tried alternate materials such as rubber cement, but settled on a thin type of tinfoil.

In 1841 he made samples of these cartridges for the army.

During tests of the foil cartridges, twenty-five rounds were fired from a musket without cleaning.

When the breech plug was removed from the barrel no fouling from the tin foil was evident.

The reception was lukewarm and the army purchased a few thousand rounds for further testing.

In 1843 the army had returned to Colt with an order for two hundred thousand of the tinfoil cartridges packed ten to a box for use in muskets.

With the money made from the cartridges Colt turns back to Morse and his cable for ideas other than detonating mines.

Colt concentrates on manufacturing his waterproof telegraph cable, believing the business will prosper alongside Morse's invention.

He begins promoting the telegraph companies so he can create a wider market for his cable, for which he is to be paid fifty dollars per mile.

Colt tries to use this revenue to resurrect the Patent Arms Manufacturing Company, but cannot secure funds from other investors or even his own family.

This leaves Colt time to improve his earlier revolver design and have a prototype built by a gunsmith in New York for his "New and improved revolver".

This new revolver has a stationary trigger and is in a larger caliber.

Colt submits his single prototype to the War Department as a "Holster revolver".
