Little cog slipping.

If it is slipping you need a new chain, freewheel and maybe a new chain rings.

Not that kind of slipping

Sorry lads: I don't mean the chain was slipping, it is the cog itself. If I hold the back wheel and push the pedal hard, the cranks go round, the smallest cog goes round, stiffly, and the other cogs stay still.

sounds like your cassette lock ring has come undone. The smallest cog only locates on the freehub spline a little less than half its thickness. I'd suggest you remove the wheel and loosen the lockring. Check the smallest cog splines are not stripped or burred and retighten.
