Kryptonite Cryptography

Oh, interesting.

The soldiers from my photo are actually from different armies - from USSR and USA. They met up by the river Elbe. In USA that day is apparently called the Elbe Day:

Elbe Day, April 25, 1945, was the date Soviet and American troops met at the River Elbe, near Torgau in Germany, marking an important step toward the end of the World War II in Europe. The first contact was made between patrols near Strehla, when First Lieutenant Albert Kotzebue crossed the River Elbe in a boat with three men of an intelligence and reconnaissance platoon. On the east bank, they met forward elements of a Soviet Guards-rifle-regiment of the First Ukrainian Front under the command of Lieutenant Colonel Alexander Gardiev. The same day, another patrol under Second Lieutenant William Robertson with Frank Huff, James McDonnell and Paul Staub met Soviet Lieutenant Alexander Silvashko with some soldiers on the destroyed Elbe bridge of Torgau.[1]

On April 26, the commanders of the 69th Infantry Division of the First Army and the 58th Guards Rifle Division of the 5th Guards Army (Soviet Union) met at Torgau, southwest of Berlin. Arrangements were made for the formal "Handshake of Torgau" between Robertson and Silvashko in front of photographers the following day (pictured). Statements were released simultaneously in London, Moscow, and Washington that evening, reaffirming the determination of the three Allied powers to complete the destruction of the Third Reich.

Adolf Hitler committed suicide in his Berlin bunker four days later.
