Hawk & the Dove #5 (On Sale: February 25, 1969) has a great cover by Gil Kane as The Dove gets all un-Dovey on us!.
"Death Has Taken My Hand" is written and drawn by Gil Kane. Sam Hodgins, a man who once saved Irwin Hall's life, is accused of robbery. Hawk and Dove discover that the two witnesses against him are members of a hot car ring. When Hawk is critically injured, Dove horrifies himself when he abandons his pacifism and beats the supposed killer unmercifully. Dove then sees that the killer is Hodgins.
After Hank Hall has made a full recovery, Hawk and Dove are back in action. They pursue an unnamed crook into a building where they encounter the Teen Titans. The story then continues in Teen Titans #21 in a neat Giordano crossover, one part written by artist Gil Kane, the other written by artist Neal Adams.
