Caesar's army rested for three days to tend to the wounded. They then gave chase to the Helvetii, who surrendered. Caesar ordered them back on their lands to provide a buffer between Rome and the even more feared Germanic tribes. In the captured Helvetian camp Caesar claims that a census written in Greek was found and studied: of a total of 368,000 Helvetii, of which 92,000 were able-bodied men, only 110,000 survivors remained to return home.
