Gustavus Adolphus and of Charles XII. The contributions made by it to
the military science of the 17th century have been noticed above. The
triumphs of the small and highly disciplined army of Charles were
often such as to recall the similar victories of the Greeks under
Alexander. The then nebulous armies of Russia and Poland resembled
indeed the forces of Darius in the 4th century B.C., but Peter the
Great succeeded at last in producing a true army, and the resistance
of the Swedes collapsed under the weight of the vastly superior
numbers then brought against them.
The _Danish Army_ has a long and meritorious record of good service
dating from the Thirty Years' War.
