The Battle of Mathias Point, Virginia (June 27, 1861) was an early naval action of the American Civil War in connection with the Union blockade and the corresponding effort by the Confederates to deny use of the Potomac to the enemy.

On April 15, 1861, the day after the small U.S. Army garrison surrendered Fort Sumter in the harbor Charleston, South Carolina to Confederate forces, President Abraham Lincoln called for 75,000 volunteers to reclaim federal property and to suppress the rebellion begun by the seven Deep South slave states which had formed the Confederate States of America.

Four Upper South states which also permitted slavery, including Virginia, refused to furnish troops for this purpose and began the process of secession from the Union.

[8] When the Thomas Freeborn arrived at Mathias Point at about 10:00 a.m. according to some sources and 1:00 p.m. according to others, its crew began to bombard the woods in order to give cover to Lieutenant Chaplin's landing party.

[11] Ward initially had accompanied the landing party, but he quickly returned to the Thomas Freeborn in order to direct more firing of the ship's cannon at the location of the Confederate force when they began their counterattack.

Ward ordered Chaplin to land again and throw up sand bag breastworks when the firing from the Thomas Freeborn temporarily quieted the Confederate force.

At this time, the Confederates, further supported by four companies of men under the command of Major R. M. Mayo, renewed their counterattack against the Thomas Freeborn and against the landing party, which was moving toward the boats.

He went on to participate in the actions against the Confederate forts at Hatteras Inlet in the fall of 1861 and was succeeded as commander of the Potomac Flotilla by Captain (later Rear Admiral) Thomas Tingey Craven.
