Stemming from Oitis, the river Dyras , or as named nowadays Gorgopotamos, sealed its name in Greek history with the blowing up and destruction of its bridge in November 1942. The collaboration of members of the Greek Resistance and British saboteurs (under the leadership of C.M. Woodhouse), after a decision made by the allied headquarters in the Middle East, led to one of the greatest acts of sabotage of WW2. The supply and transport of the German forces was interrupted for six weeks and although the impact of this action was consequently very limited for the North African front, the night of the explosion raised feelings of admiration in the whole of occupied Europe and elevated the overall standing of the Greeks.
