[Matakari]

Good evening, detective work is apace now to discover the Heroes.
Confirmation for the following would be appreciated, thanks!

12(A) Gosh, old Oscar gains medal! (4) : ?DS? ( ODSO )
16 (A) Fourth man to mount horse (4) : ?E?? ( SETH )
24 ( A ) Pigeon avoids master gardener (4) : ?OE? ( HOER )

And help with…
38 ( D ) Lass a long time cuddling knight (5) : ?E???

Yes to all 3 across clues.
38 d- 4 letter word for a long time round N for knight.

Matakari, I'm sure you saw the massive hint for the theme on your earlier batch, there won't be much detecting needed.

Better luck with the next Pabulum.

Should have said your E is wrong in 38 down.
