There was exterior VFX on the first battle (or sneak attack), showing just the Enterprise and not a glimpse of the enemy vessel. An actual two-party space battle could be shown in the stead of these shots - even though the original shot of torpedoes slamming onto the Enterprise admittedly is a very effective one.
There's no "slot" for the battlefleets mentioned in the dialogue towards the end of the episode, and no dramatic need for them.
In fact, showing them would rather ruin the mood of the episode, as the whole plot hinges on our two heroes seeing X and thinking Y when the truth in fact is Z. No "objective truth" of matters should be shown in the episode, IMHO. We don't really want to see the scene where the Klingons (think they) execute 200 Organians, either.
