Bulgarian Infantry Patrolling the Frontier at Doudnitza

Bulgarian Mounted lnfantry march past. These are picked men, and do duty along the different passes. They are very fine horsemen, and keep an eye on miles of frontier. 
The last section shows a squad of this mounted patrol proceeding through a steep defile, the path being too narrow to allow of other order of procedure except in single file.
