Any tips on how to get them out without making more mess of the timber?

When hit backwards they just bend, the heads are firmly stuck :-(

Tried punching back out after the pointy end metal fatigued off
leaving the embedded nail flush but can't get it
moving!

TIA


Put the timber somewhere really dry so that it will shrink
away from the rusty nails and then you might stand a chance
of getting the nails out.

Could take a while to dry thoroughly.
