[1] The Texas Navy was officially formed in January 1836, with the purchase of four schooners: Invincible, Brutus, Independence, and Liberty.

Unlike Sam Houston, Lamar was an ardent supporter of the Texas Navy and saw the urgent need for its continuation.

The Secretary of the Navy, Memucan Hunt, Jr. spent over $10,000 equipping the Potomac for service, but as the sale had never been completed due to the Texas Congress not having approved the expenditure of funds to purchase Potomac, the work was suspended without being completed.

[5] In 1843, with the Potomac unfit to serve as a warship, she was transferred to other public use with the Galveston Harbormaster as a pilot ship.

She ended her career in the Texas Navy never having left port or fired a weapon in conflict.
