The Cross of Valour (Polish: Krzyż Walecznych) is a Polish military gallantry decoration. It was first introduced by the Council of National Defence on 11 August 1920. It is awarded to an individual who "has demonstrated deeds of valour and courage on the field of battle." It may be awarded to the same person up to four times.The medal is given only in wartime or shortly after.
Obverse bears the words, "NA POLU CHWAŁY" ("ON THE FIELD OF GLORY"), while the reverse bears the word, "WALECZNYM" ("TO THE VALIANT"), and the date "1920", "1939" or "1944," depending on date of institution.

This version of the Polish Cross of Valour 1920 was instituted in 1920 and during WWII the Polish Government in exile had another ribbon designed.
Medals issued under authority of the Polish Government in exile in London, retained the originating medal version date 1920. Polish military forces who fought alongside the Soviets 's during WWII had other versions of the Polish Cross of Valour struck with the dates "1939" and "1944".
