US Armory Buildings. Harper's Ferry, W. Va. at time of Civil War

Here is a GREAT postcard I bought for pocket change from the Jefferson County Museum in Charles Town West Virginia......  Go there and buy one for yourself!  On the back of this one, it says-

"Of the many places that were in a constant state of siege during the Civil War, Harper's Ferry suffered most heavily.  The Government arsenal and armories located there were destroyed by Federal Troops to prevent their capture by the Confederates.  These buildings were erected sometime after the Revolutionary War, and it was there that many of the old flint lock rifles were made that were used in the War of 1812."
