When Last We Left Flash Gordon (ahh-ahhh...)...
...wow, the opening caption covered the plotline perfectly!
You'll note Flash is wearing a more ornate outfit while Patch's clothes are the same, but mis-colored (as is her hair, which was silver/white in the previous chapter)!
Illustrated by Gil Kane, replacing Wally Wood.
The writer is unknown.
Though Flash had his own comic at this time, this three-parter appeared in the back of The Phantom's title from the same publisher, King Comics.
(All the King Comics books did this, presumably to expose their target audience to other titles they might not otherwise read.)

The particular tale appeared in the back of The Phantom #19 (1966).
