Archaeologists say they have proven for the first time that Julius Caesar set foot on what is now Dutch soil, destroying two Germanic tribes in a battle which left around 150,000 people dead. The two tribes were massacred in the fighting with the Roman emperor in 55 BC, on a battle site now at Kessel, in the southern province of Brabant. "It is the first time that the presence of Caesar and his troops on Dutch soil has been explicitly shown," said archaeologist Nico Roymans.
