Fort Francis E. Warren Postcard

Marie's Postcard Collection.  Fort Francis E. Warren.  On the back it says Fort Francis E. Warren named after the grand old Senator from Wyoming. 

His first name was Fort?

It goes on to say in bygone days it was known as Fr. D. A. Russell and was established during the days of the Indians and Buffalo to protect the Union Pacific Railroad. 

It must have been protecting them mostly from the Buffalo - because in those bygone days it was a sport for gentlemen sportsmen to shoot buffalo from the comfort of their RR car.
