David J. Naylor

David Johnson Naylor served in the United States Navy during the American Civil War and became one of the enlisted sailors whose courage during the Battle of Mobile Bay was recognized with the Medal of Honor. At the time of his heroic action, Naylor held the rating of Landsman and served aboard USS Oneida, a Union warship that took part in one of the most important naval battles of the conflict.

A Landsman was an entry-level enlisted sailor in the nineteenth-century United States Navy. Men in this rating performed essential shipboard duties and could be assigned to gun crews, deck work, handling lines, ammunition movement, and other tasks necessary to keep a warship functioning. During combat, every member of the crew had a defined responsibility, and maintaining those duties under heavy enemy fire was crucial to the survival and effectiveness of the ship.

By 1864, Union naval forces were attempting to close Mobile Bay, Alabama, one of the Confederacy’s remaining important Gulf Coast ports. The operation was led by Rear Admiral David G. Farragut and brought together a powerful Union fleet against Confederate forts, naval vessels, underwater mines, and the ironclad CSS Tennessee.

On August 5, 1864, the Union fleet entered Mobile Bay. The attacking ships faced heavy fire from Fort Morgan and other Confederate defenses. The approach was particularly dangerous because the entrance to the bay had been protected by underwater mines, then commonly called torpedoes.

Early in the battle, the Union monitor USS Tecumseh struck a mine and sank rapidly. The loss created confusion within the attacking formation, but Farragut ordered the fleet to continue forward rather than abandon the attack.

USS Oneida was among the Union vessels that pressed into the bay. The ship came under severe enemy fire as the battle developed into a close and violent naval engagement.

David J. Naylor remained at his duties aboard Oneida during the fighting. As an enlisted sailor, his role placed him directly within the operational life of the ship at a time when Confederate gunfire was striking Union vessels and crews were working continuously to maintain combat effectiveness.

The Battle of Mobile Bay demanded discipline as well as physical courage. Sailors had to continue handling weapons, ammunition, rigging, machinery, and damage-control duties while exposed to gunfire, smoke, splintering wood, and the possibility of catastrophic damage to their vessel.

Naylor’s conduct during the engagement distinguished him sufficiently for formal recognition by the United States Navy.

For his actions during the Battle of Mobile Bay on August 5, 1864, David J. Naylor received the Medal of Honor.

The Navy Medal of Honor had been authorized during the Civil War, beginning in 1861, and was the earliest form of what developed into the highest military decoration of the United States. During the Civil War period, it was frequently awarded to enlisted sailors and Marines who demonstrated exceptional courage, devotion to duty, or distinguished conduct during combat.

Naylor’s award belongs to this original naval tradition of the Medal of Honor. His decoration was formally recognized under General Order No. 45, dated December 31, 1864.

For the project database, his decoration is represented under the historical category Medal of Honor 1862–1912 Navy. No additional star, clasp, bar, or other device is associated with his Medal of Honor.

The Battle of Mobile Bay itself became one of the most celebrated Union naval victories of the Civil War. After forcing passage into the bay, the Union fleet confronted the Confederate naval force, including the powerful ironclad CSS Tennessee.

The fighting eventually ended with the defeat and surrender of Tennessee and the establishment of Union dominance inside Mobile Bay. Although the city of Mobile did not immediately fall, the Confederate ability to use the bay as a major blockade-running route was severely reduced.

Naylor’s service aboard USS Oneida therefore placed him directly within a strategically important operation that strengthened the Union blockade and reduced Confederate access to the Gulf of Mexico.

His Medal of Honor reflects the contribution of enlisted sailors to that victory. Naval battles were not won only by admirals and ship captains. They depended on ordinary sailors who continued performing their assigned duties while ships were under direct enemy fire.

Naylor survived the Civil War and lived for many decades after his wartime service. His long life extended into the twentieth century, and he was still living after the creation of the Navy’s Civil War campaign decoration.

In addition to his Medal of Honor, Naylor’s final project medal record includes the Navy Civil War Medal. This decoration was created decades after the Civil War to recognize qualifying service by members of the United States Navy during the conflict.

The Navy Civil War Medal was separate from the Army’s Civil War Campaign Medal. It reflected naval service during the war and was designed specifically for sailors and other qualifying naval personnel rather than Army veterans.

Because Naylor survived well beyond the period when the Navy Civil War Medal became available, his project record recognizes this decoration as part of his Civil War service history.

No additional clasp or device is associated with the Navy Civil War Medal in his final record.

David J. Naylor’s final medal history therefore consists of two decorations: the Medal of Honor 1862–1912 Navy and the Navy Civil War Medal.

His military career is most closely associated with surface naval warfare. His defining combat experience took place aboard USS Oneida during the Battle of Mobile Bay, where he served as an enlisted sailor in direct naval combat against Confederate forces.

His story represents an important part of Civil War naval history. While senior officers directed fleets and ships, sailors such as Naylor carried out the demanding work that allowed those vessels to continue fighting.

The Medal of Honor permanently linked his name to the events of August 5, 1864. His recognition was not based on rank or command authority, but on his conduct as an enlisted sailor during one of the most dangerous naval operations of the war.

David Johnson Naylor is therefore remembered as a United States Navy Landsman, a member of the crew of USS Oneida, a veteran of the Battle of Mobile Bay, and a Medal of Honor recipient whose service became part of the broader history of Union naval victory during the American Civil War.
