I think I've got some answers, but I'm not sure of them.

22d Energy to burst out at the start (5) - - - - O Could this be GUSTO?

If 22d is GUSTO: 21a Turn back in military order for C-in-C (6) - H - G - N SHOGUN?

25a For execution, does not reveal fateful day (4) - D - S if GUSTO IDES?

13a It grows in three seconds (4) - O - S No ideas for this one.

As usual thanks for help.

13a moss - mo=second mos=2seconds moss=3seconds

22d yes gust + o(ut)
25a (h)ides...for execution = remove first letter of hides
22d yes shogun - turn = go reversed inside 'shun (military order)

21a Shogun ....Go +shun!

25a (H) ides

I have GUSTO, IDES and SHOGUN for those answers.
Shun (military order) with go (turn back)
gust is energy o is the first letter of out
ides from ides of march

Thanks very much JMR27. Kicked myself for not seeing 'shun.
