It wasn't Silver Banshee. It was Jeannette who is A banshee and has similar powers. It happened in Secret Six #12



Her banshee wail made Diana experience her death, which--similar to how its described in the Superman pic above--put WW down pretty hard for a period. It also wound up knocking Jeannette herself out, which was why she only busted it out in an emergency (Diana was kicking her ass pretty thoroughly until that point).
