Resistance groups used symbols that were placed on walls, trees, letters, and everywhere that each had a specific meaning. Members were called by code names, and operational units had specific cryptonym or symbols. The underground newspaper published coded articles and drawings that resistance fighters would know to look for and understand the meaning of the message. Even poetry was used as a means of sending coded messages or identifying oneself as a member of a resistance group to other members (Espionage). The resistance groups also had designated meeting places. Some of these meeting places were made specifically for a single resistance group, others were made for multiple resistance groups, and even some were made to meet with allied commanders or governments that were associating with the resistance
