Is it possible for a quarter turn to be blocked by an enemy unit or friendly unit that it cannot interpenetrate. For example in the diagram below A and B are Cav (40mmx30mm in 15mm scale). A is roman and is facing to the right, B is Parthian facing to the bottom. there is less than 10mm between A and B. If some roman unit charges B in the flank can B evade?

B

To do so requires B to make a quarter turn, but this would cause it to overlap A. If however B was 40mm x 40mm based it could evade (turning would not result in overlap).

In this game base width is not very important, so i think you can evade.

And yes, in my group we use 40x40 bases for everithing except LI, it's much easy

I believe it depends upon the space available to the unit that wishes to turn.
As you present the question the diagram looks like this :-

A
A

BB .X
. . . X

Unit BB should turn through 90 degrees by moving its front left corner onto the position occupied by its front right corner. Doing this would place the right edge of the unit over unit A, but the intention of greater simplicity lying behind the rules seems to permit a degree of flexibility which would allow this movement.

However it is prohibited where there is insufficient space to turn through 90 degrees as in the following diagram where units B, C and D are cavalry or light infantry

A
A
BB .X
CC .X
DD

Here, turning either unit B or unit C in order to evade would be prohibited because neither of them has sufficient space to manoeuver. If the unit attacked in the flank survives, at the start of the following turn that unit would be turned to conform with the attacker, displacing its friends (see p. 53),

That said, I believe that neighbouring units would not be allowed to turn to support the defender if there is insufficient space, though this would need to be confirmed by others.

As such, this is actually a good reason for retaining the 40x30 base to create the devastating effect of a column being charged in the flank.
