He was entrusted with the transportation of the corpse of the Emperor when Julian died during his military campaign against the Sasanids.
This was a sign of great honour, since the holding of multiple consulates had been reserved for members of the imperial family since the reign of Constantine I. Merobaudes was likely a firm supporter of Count Romanus, the proconsul of Africa.
[2] In 378 Gratian ordered Merobaudes to withdraw his troops eastwards to reinforce the Eastern Emperor Valens in his planned attack on the Goths, who had begun to revolt after relocating to Roman territory when displaced by invading Huns.
Merobaudes decided to leave troops behind in Gaul, preventing a disaster when the Alemanni decided to invade after learning of the planned Roman withdrawal and leading to a massive victory for Gratian's army at Argentia, killing 30,000 Alemanni.
According to ancient sources, in 383 Merobaudes supported the usurper Magnus Maximus and was put to death by the Emperor.
