Masked and double-identitied Nighthawk took over the slot of the similar Vigilante with #5 (and missed #6). Western 5 came out in the same month as DC's Dale Evans Comics, where writer Joe Millard's best-known DC work, the Sierra Smith back-up strip (not to mention his Dale Evans stories) begins. Millard's run on Nighthawk coincides, as it happens, with Charles Paris's run of pencils and inks on the feature.
These are all of Millard's Nighthawk stories. I can see that #13 and 14's are by a single author, although one I can't put a name to; an Alan Brennan is known from the Who's Who to have written Nighthawk in 1950, so take that as you will. In another few issues Cameron and Fox write their first Nighthawks.
