sentences:  The 41-year-old Ingersoll was drafted into the military; when he returned after the war, he found a paper that was less lively and well-written than it had been under his leadership, and with the pro-communist and anti-communist liberals writing at cross purposes.The paper never quite recovered and ceased publication in 1948, an early victim of the Cold War (and of Field's increasing interest in the "Chicago Sun" rather than "PM").Ingersoll later wrote numerous books about his service in World War II.
