[Star Wars ANH] During the attack on the Death Star, why didn't the Empire deploy, like, a lot more TIE fighters?

It seemed like they were pretty conservative in the number of fighters they launched to combat the attacking rebel fighters.  Why not launch 2,000 TIE fighters, to swiftly overwhelm and destroy the rebels?

At that moment, Tarkin was the embodiment of arrogance. He did not think the Rebels stood a chance, and paid almost no attention to the pitiful attack from a handful of fighter craft. In his eyes, the Death Star was invincible, and moments away from destroying the primary Rebel base. Remember, he shot down the idea of evacuation when the Rebel plans had been analyzed, and his engineers recognized the weakness they were gunning for. 

So the TIE response was literally just following the bare minimum of military protocol, and possibly not even ordered from him, but a lower officer responding so said protocol. 

If any other (competent) commander had been in charge of the Death Star, it's likely the fighter response would have been much heavier. But perhaps it was the will of the Force that Tarkin was so overconfident.
