In Star Wars: Episode 1 - The Phantom Menace, in the climactic battle, Anakin Skywalker gets inside the command center for droids and destroys it from the inside. After escaping, one other pilot says:
BRAVO THREE: Look! One of ours! Outta the main hold!!
Did anybody find out it was Anakin who blew up the command center? Did Anakin brag to anyone about it? Or was Anakin not as cocky as older Anakin, and kept such an achievement to himself?
In the original script, they found out almost immediately after landing.
RIC OLIE : We're all accounted for. Who flew that ship?
ANAKIN sheepishly opens the cockpit and stands up. All the PILOTS stare in amazement.
ANAKIN : I'm not going to get into trouble, am I?
The adult novelisation indicates that Obi-Wan found out shortly after that and considered it a sign that Anakin was the Chosen One the prophecies were talking about.
But it was a nine-year-old boy who had saved them all. Even without knowing exactly what he was doing, Anakin Skywalker had flown a starfighter into the teeth of the Federation defense, penetrated their shields, landed in the belly of the Neimoidian flagship, torpedoed the ship’s reactor, and set off a chain reaction of explosions that destroyed the control station. It was the destruction of the central transmitter that had caused the droid army to freeze in place, their communications effectively short-circuited. Anakin claimed not to have attacked with any sort of plan in mind or fired his starfighter’s torpedoes with any expectation of hitting the reactor. But after hearing the boy’s tale and questioning him thoroughly, Obi-Wan believed Anakin was guided by something more than the thinking of ordinary men. That extraordinarily high midi-chlorian count gave the boy a connection to the Force that even Jedi Masters on the order of Yoda might never achieve. Qui-Gon, he now believed, had been right. Anakin Skywalker was the chosen one.
In Star Wars: The Clone Wars S04E09 "Plan of Dissent", Fives is discussing attacking a droid control ship and says:
General Skywalker blew up a droid control ship when he was just a kid, and he told me the trick is hitting their main reactor from the inside.
So we know that Anakin told at least one person directly that he was responsible for blowing it up. Given his showboating personality, it's likely that Fives wasn't the only one that he told.
Yes, people found out. In a Clone Wars episode (which is canon) from the "Darkness on Umbara" arc, a clone mentions how Anakin took out the command ship.
