With the doors to EC open to him Kurtzman started getting regular work from the publisher in 1950. That spring, EC's "New Trend" line of horror, fantasy, and science fiction comics began, and Kurtzman contributed stories in these genres. His income doubled over the previous year's. In late 1950, he began writing and editing an adventure title, "Two-Fisted Tales", which he proposed as a comic book in the vein of Roy Crane's popular comic strip, "Captain Easy". The comic book differed in offering realistic stories in place of Crane's idealism, a degree of realism not yet seen in American comics. The war stories of "Frontline Combat" followed in mid-1951. The stories were not only about modern war, but also derived from deep in history, such as the Roman legions and Napoleonic campaigns. Kurtzman rejected the idealization of war that had swept the US since World War II. He spent hours in the New York Public Library in search of the detailed truth behind the stories he was writing, sometimes taking days or weeks to research a story. His research included interviewing and corresponding with GIs taking a ride aboard a rescue plane, and sending his assistant Jerry DeFuccio for a ride in a submarine to gather sound effects. (DeFuccio's first field report from this assignment was a 10-word telegram to Kurtzman reading "MANY BRAVE HEARTS ARE ASLEEP IN THE DEEP GLUB GLUB.") The stories gave a sympathetic look to both sides of a conflict, regardless of nationality or ethnicity. He sought to tell what he saw as the objective truth about war, deglamorizing it and showing its futility, though the stories were not explicitly anti-war.
