Using FTFB interceptors

I had an unusual situation come up the other day and while what's done
is
done, neither side is entirely comfortable with it.  I'd like to get a
consensus on the best way to play it.

I'll set the scene with a simplified but fairly accurate analogy.

I'm the NAC and have a squadron of destroyers and a fleet carrier.  My
opponent is the ESU.  My fighters are interceptors and his are attack
fighters.  Obviously, I wish to use my fighters to protect my ships from
his
fighters.  However, I have many small ships and so I cannot screen all
my
ships.

On turn 3, say, he moves a group designated A to attack a destroyer.  I
move
a group of interceptors designated 1 into base to base contact to
initiate a
dogfight.  (We play that he must dogfight; is this generally agreed upon
?).

Both sides have fighters surviving after the dogfight.

On turn 4, his fighters wish to break from the dogfight to attack a new
target.  The NAC interceptor group 1 takes a free round of attacks at
ESU
attack fighter group A before they move (free meaning they are not
retaliated upon, it does cost combat endurance).  Group A moves away,
into
an attack position.  Group 1 is free to follow, and moves into base to
base
contact with A again.  (I assumed 1 was free to follow.  Any dissenters
?)

Is this a dogfight, or is Group A free to attack ?  (I would say A is
free
to attack, 1 cannot attack A.  Had 1 moved into contact with a different
group B, same story).

ESU attack fighter group A also has an even juicier target just outside
of
range.	A expends combat endurance to reach attack range for that
target,
then more to attack it.

Does A come under attack for leaving base to base contact with NAC
interceptor group 1 ?  (I said yes).

Can the NAC interceptors burn combat endurance to maintain base to base
contact with Group 1 ? (I said yes).

This was an interesting conundrum.  I'd always assumed that if there was
fighter parity, fighters would effectively cancel each other out.  If
one
side had interceptors and fighter numbers were equal, the interceptors
were
more than capable of blunting the enemy fighter attack.  What this
sequence
indicated was that the interceptors would get two attacks on the enemy
fighters before the enemy could attack a target ship, but as long as the
enemy was willing to flee a dogfight to make its attack run, it would
indeed
make the attack run.
