Thomas Jenkins

He Faced Vicksburg’s Guns Without Flinching

Thomas Jenkins was born in 1831 in Australia and later entered the United States Navy, where his service during the American Civil War brought him into one of the most dangerous naval operations of the Vicksburg Campaign. Serving as a seaman aboard USS Cincinnati, Jenkins demonstrated remarkable composure under intense Confederate fire on May 27, 1863, conduct that earned him the Medal of Honor.

By the spring of 1863, Union forces were closing in on Vicksburg, Mississippi, a heavily fortified Confederate stronghold overlooking the Mississippi River. Control of the city was strategically vital. As long as Vicksburg remained in Confederate hands, the South maintained an important position on the river and continued to interfere with Union efforts to control the Mississippi completely.

The Union campaign combined operations by Major General Ulysses S. Grant’s army with the naval forces operating on the river. Among the vessels supporting those operations was USS Cincinnati, a heavily armed Union gunboat designed for combat on the western rivers.

Jenkins served aboard Cincinnati as a seaman. His duties placed him within the disciplined system that kept the warship operating during battle, where every sailor had an assigned role and the effectiveness of the entire vessel depended on men remaining at their stations while enemy fire struck around them.

On May 27, 1863, Cincinnati was ordered against the Confederate defenses at Vicksburg.

The mission placed the gunboat directly under the fire of powerful shore batteries.

As Cincinnati approached the Confederate positions, enemy artillery opened with severe accuracy. Heavy shells struck the vessel repeatedly as its crew continued operating under increasingly dangerous conditions. The engagement became a brutal test of endurance for the sailors aboard.

James Jenkins—known in the official record as Thomas Jenkins—remained conspicuous for his coolness and bravery under that fire.

His Medal of Honor recognition was based not on a later embellished story, but on the simple and powerful fact that he maintained his courage and effectiveness while Cincinnati was subjected to extraordinarily accurate Confederate artillery.

The situation aboard the gunboat deteriorated rapidly.

Enemy fire inflicted serious damage on Cincinnati, and the vessel eventually became unable to remain afloat. The gunboat was lost during the action, but the conduct of men such as Jenkins became part of the official record of the battle.

The attack demonstrated the extreme danger faced by Union sailors operating on the Mississippi River. Unlike engagements fought in open water, river warfare often forced vessels to approach fixed batteries positioned on elevated ground. Confederate artillery crews could concentrate their fire on ships moving through restricted channels, leaving the crews aboard those vessels with limited room to maneuver.

Jenkins faced those conditions at Vicksburg.

Under concentrated enemy fire, he displayed the calmness expected of an experienced sailor and the courage required to continue performing his duty while the ship around him was being struck.

For his conduct aboard USS Cincinnati on May 27, 1863, Jenkins was awarded the Medal of Honor.

His award was recorded under Navy General Order No. 17, dated July 10, 1863.

The wording of his original Medal of Honor citation was direct and concise. It recognized him as conspicuous for coolness and bravery under severely accurate fire.

Those few words captured what made his service exceptional.

There was no need for an elaborate description. Jenkins had remained composed in circumstances where the consequences of a single enemy shell could be fatal. His courage was demonstrated through steadiness under fire while serving aboard a warship being heavily engaged by Confederate batteries.

The Medal of Honor awarded to Jenkins survives as a physical reminder of that service.

His Civil War-era Navy Medal of Honor represents one of the earliest generations of the decoration, created during the conflict to recognize extraordinary conduct by sailors and soldiers. The award connected his name permanently with USS Cincinnati and the naval operations against Vicksburg.

Jenkins’s broader qualifying service during the American Civil War is also represented by the Navy Civil War Campaign Medal.

The Navy Civil War Campaign Medal was authorized in 1908 to recognize qualifying service by personnel of the United States Navy and Marine Corps during the Civil War. The date 1908 represents the authorization of the decoration, not the date of Jenkins’s combat action or Medal of Honor award.

For Jenkins, the Medal of Honor and the Navy Civil War Campaign Medal represent two different aspects of his military service.

The Medal of Honor recognizes his specific courage aboard USS Cincinnati under the Confederate guns at Vicksburg on May 27, 1863.

The Navy Civil War Campaign Medal represents his broader qualifying naval service during the American Civil War.

No separate ribbon devices are associated with either decoration in his verified record.

The Vicksburg Campaign ultimately became one of the most important Union victories of the Civil War. After weeks of siege operations, Vicksburg surrendered on July 4, 1863. The victory gave the Union control of the Mississippi River and divided the Confederacy geographically, dramatically changing the strategic situation in the western theater.

Jenkins had played his part in the dangerous naval operations that helped place relentless pressure on the Confederate stronghold.

His story is especially powerful because the official record does not depend on exaggerated claims.

It records a sailor under severe and accurate enemy fire.

It records coolness.

It records bravery.

And it records conduct considered worthy of the nation’s highest military decoration.

On May 27, 1863, as Confederate artillery battered USS Cincinnati beneath the defenses of Vicksburg, Thomas Jenkins remained steadfast at his duty.

For that courage under fire, he received the Medal of Honor.

Together with the Navy Civil War Campaign Medal recognizing his broader qualifying wartime service, his decorations preserve the legacy of a Union sailor whose calm determination endured while one of the Civil War’s most formidable Confederate strongholds poured fire onto his ship.
