Au contraire, not according to the B&W TV series from approx. 1955-1960 (with Richard Greene playing Robin).
...with Richard Greene playing Robin...
And the role of Little John was played by A. Nameless Gerbil
And, Robin was captured after the archery competition in the Errol Flynn movie
Oh come on, the Sheriff or his men would occasionally grab him, but imprison him in the dungeon? You’d have to cite the episode for me to believe it.
Not even Richard Greene was that inept a Robin as I recall.
We’re talkin’ ROBIN HOOD here, a guy who could shoot arrows into the end of other guys arrows in the bulls-eye, not some wimpy hero who’d just shoot guns out of the bad guy’s hands.
