Timeline question.

No: HPFGUIDX 87694

I was reading the lexicon last night, and it said that in 1980 Karakroff and
Dolohov are captured and sent to Azkaban.  Now that is at least a year
before LV's failed attack on HP.

In book 4, When Harry finds Dumbledore's pensieve and sees the court
scenes.  Karakroff outs Snape as a DE when he is trying to buy his way
out.  Now, Dumebldore verifies that Snape is a spy and no longer a DE,
etc, etc.  If LV was still at full strength at this time, something is 
definitely
up.

Now, what my question is.  When was this trial?  Was it before the Potter's
attack or after?  Did those two DE's stay in Azkaban for over a year before
the trial or not.

Any thoughts?
