Apparently Callimachus was in command of the Athenian forces at Marathon, but he was killed in the battle, and Miltiades managed to get most of the credit for the victory.
Herodotus says,
"Miltiades' words prevailed. The vote of Callimachus the War Archon was cast on the right side, and the decision to fight was made."
( Book 6 sect 109)
And let's not forget the strategic planning of Themistocles.
And you know what happened to Militiades. After the victory, he tried unsuccessfully to regain control of the Aegean islands that had capitulated to the Persians in 489BC, but he did not have a sufficient naval force to accomplish this task.
Upon failing to achieve the blockade of Paros, he was imprisoned at Athens for his defeat, dying soon afterward of a wound received at Paros.
This is how the victor of Marathon rewarded.
