Flag of the 2nd Mass. Cavalry, 1865
The Massachusetts 2nd Regiment Cavalry, while organized by the Bay State, consisted largely of California volunteers who shipped east at their own expense, beginning with the "California Hundred," organized in San Francisco in 1862 and arrived in Massachusetts in 1863. This California origin is indicated on their flag by the Californian "Eureka" motto and what appears to be the California state seal.
The unit saw extensive service in the Eastern theater and was present during the final campaign which forced Lee's surrender -- as proudly marked by the notation "Appomattox Ct. House" as the last of their listed actions. They also marched in the Grand Review of the Armies held in Washington May 23, 1865, where it seems likely this flag would have been displayed.
A rare, dated period image celebrating the conclusion of America's hard-fought struggle.
