Note 433 — Chapter VIII · (Year of Rome 700.) (Book V. of the “Commentaries.”) MARCH AGAINST THE TREVIRI—SECOND DESCENT IN BRITAIN.

The siege machine called testudo, “a tortoise,” was ordinarily a gallery mounted upon wheels, made of wood strongly squared, and covered with a solid blindage. It was pushed against the wall of the place besieged. It protected the workmen employed either in filling the fosse, or in mining the wall, or in working the ram. The siege operations of the Gauls lead us to presume that the camp of Cicero was in a fort surrounded by a wall. (See, on the word falces, note (1) on p. 143.)
