Jugo-Slavian Troops On Hungarian Jugo-Slav Border A detachment of Jugo-Slavian infantry photographed as they march through a village towards the frontier of Jugo-Slavia and Hungary. They use MacKintosh capes to protect then from the rain as they go. Like other European countries Jugo-Slavia is keeping all her frontiers well manned in spite of the protests of her neighbors that they want nothing but peace. April 24, 1939. (Photo by Keystone).
