Connect 4 Mikrotik's via Wifi

Hello. I’ve got a 4 Mikrotik RB951 that should be connected via WIFI. They can be connected one by one only.

Like that:

MikrotikA >>>>>>>>> MikrotikB <<<<<<<<<< MikrotikC <<<<<<<<<< mikrotikD
I want to make bridge between all this Mikrotik’s (one subnet)

For example I make AP bridge on MikrotikB
Then I make station bridge on MikrotikA.
And I make station WDS on MikrotikC
So there’s will be 3 Mikrotik in wireless bridge

But then I need to connect mikrotikD to this bridge.
So MikrotikD should be connected to MikrotikC. But how?
When MikrotikC in station WDS mode, i can’t connect to it from MikrotikD (didn’t see AP)
Should I use WDS slave mode on MikrotikC then?
Thanks and sorry for bad english.

make a dynamic WPS -mesh , why you want to connect them like this !

Do you really need bridges? Static wds with routing between all hops would be better, I guess. And would everytime find the way for packets if routing is set correctly.
