About to be homeless, long term - climate is North west Europe, what do I need?

So far I’ve thought of,
>backpack
>rope
>shelter (tent/basher ties to two trees?)
>sleeping bag
>clothes
>water bottle
>knife, fork + spoon
>boots

I’d really appreciate any ideas, I have a few other things also such as matches/bic, but I know I’m missing a lot and want to be prepared.

Thanks lads
