 A few of the Robinsons actually tried to actively take revenge on the occupying forces . The most famous of these , who became a local legend , was an individual known only as " Ares " ( after the Greek god of war ) , described by Gluth @-@ Nowowiejski , based on interviews with the Robinsons he conducted . Ares , active in the Śródmieście district , staged numerous ambushes of German soldiers , in at least one case using an improvised explosive device . According to Gluth @-@ Nowowiejski 's sources , he would leave behind graffiti of his name , as well as slogans such as " Hitler kaput " . Other messages included communications to the German soldiers . In one case he dumped a body of a soldier he had killed with the note : " This awaits all of you in Warsaw " . In another he wrote : " Ares is a ghost , not matter – your search for him is useless " . Eventually , Ares met his demise when the Germans left some poisoned food for him to find . Soon they discovered a man in the ruins who was obviously sick from having eaten it . He shot at them before taking his own life . According to some sources , other individuals took on Ares ' struggle but used the names of other Greek Gods as their signature .
