Researchers knew about the large site - close to the German town of Hermeskeil, near the French border - since the 19th century but lacked solid evidence about what it was.
"From an archaeological point of view our findings are of particular interest because there are only few sites known that document Caesar's campaign in Gaul," researcher Sabine Hornung, of Johannes Gutenberg University of Mainz (JGU), told LiveScience in an email.
"Some remains of the wall are still preserved in the forest, but it hadn't been possible to prove that this was indeed a Roman military camp as archaeologists and local historians had long suspected," Hornung said.
Hornung and her team began work on the site in March 2010, first mapping the fort's dimensions. They found that the military base was made up of a rectangular earthwork enclosure with rounded corners, covering about 45 acres (182,000 square metres).
They also found an 18-acre (76,000-square-metre) annex that incorporated a spring, which may have supplied water to the troops.
During excavations the next year, they found one of the gates of the fort. In the gaps between stones that paved the gateway, the team found shoe nails from the sandals of Roman soldiers and shards of pottery that helped confirm the site's date.
The underside of the shoe nails showed a pattern of a cross with four studs, which was typical for that time period.
The researchers think the tiny nails, just an inch or 2.6 centimetres in diameter, likely loosened from the sandals as soldiers walked along the path.
"The most exciting part of our discovery is that it seems possible to link the military camp to an episode of world history by trying to make our dating just a little more precise," Hornung said.
"It is already highly probable that legionaries were camped there during the Gallic War, but hopefully one day we can tell, whether this happened in 53 or rather 51 BC," Hornung added.
The fort is just 5 kilometres from an Celtic settlement once inhabited by the Treveri tribe. That ancient town had monumental fortifications known as the "Hunnenring" or "Circle of the Huns," but was abandoned around the middle of the first century BC.
The discovery of the nearby Roman fort hints that the Treveri tribe's flight likely was linked to Caesar's troops moving in, the report said.
"It is quite possible that Treveran resistance to the Roman conquerors was crushed in a campaign that was launched from this military fortress," Hornung said.
The findings have been published in the German journal Archaologisches Korrespondenzblatt.
