of Christendom at the present day, may easily be vanquished, since any slight mishap, and the least failure in the steadiness of his men, may deprive him of victory.
And what takes from our armies the capacity to renew their strength is, that provision is now no longer made for one division being received into the ranks of another, which happens because at present an army is arranged for battle in one or other of two imperfect methods. For either its divisions are placed side by side, so as to form a line of great width but of no depth or solidity; or if, to strengthen it, it be drawn up in columns after the fashion of the Roman armies, should the front line be broken, no provision having been made for its being received by the second, it is thrown into complete disorder, and both divisions fall to pieces. For if the front line be driven back, it jostles the second, if the second line endeavour to advance, the first stands in its way: and thus, the first driving against the second, and the second against the third, such confusion follows that often the most trifling accident will cause the ruin of an entire army.
