Here's how far I got before dark today in clearing the Russian vine and ivy in my garden.
Actually, not very far at all, so far.
The Russian vine tends to twist it's stems around each other, and also around the ivy branches and few briars and brambles that have also grown in amongst it all. Which makes it impossible to just pull stems apart. Instead, I am having to just about cut through each individual stem with the secateurs one at a time; and also work my way through the tangle just a few inches at a time. Hard work but, as long as the weather stays reasonably dry, I'll keep at it until everything has been cleared.
If you look carefully at the nearest gable wall of the first stone shed, you will see that it is leaning inwards at the top. The inner stonework has been damaged, and I reckon the top of it will collapse inwards as I remove the overgrowing branches (which I think are all that's stopped it from falling up till now).
But... don't start worrying, gang. My name is Marty, not Gary, and I will take every possible safety precaution.
You might even notice I'm using a proper metal ladder to reach the top of the boundary wall. No standing on chairs for me.
