Best way to get a stuck Defender, unstuck?

[Muddle238]

So as embarassing as it was, last winter I managed to get my Defender 90 stuck in a field. A completely flat, grassy field. Recent wet weather had the ground pretty boggy, and upon leaving the firmer stuff along the side of a hedgerow, it sank, lost all grip and ended up sitting in its own ruts. No matter how much back and forth I tried either gently or fiercly would get it to move, in the end a JCB dragged it the 10 yards or so back to the firm stuff.

I'll say now it's bog standard, 2003 Td5 pick up, no winches fitted etc. Has anyone got any tips as for the best way to somehow single-handedly drive it out, using nothing but technique? Yes, this was an embarassing Defender moment

Cheers for the input, think I'm going to get myself some boards as a minimum. Any excuse for a eBay foraging session evening, find some decent equipment and then a weekend of testing said equipment.
