Gustavus Adolphus of Sweden - Legacy As A General

Legacy As A General

Gustavus Adolphus was an extremely able military commander. His innovative tactical integration of infantry, cavalry, logistics and particularly his use of artillery, earned him the title of the "Father of Modern Warfare". Future commanders who studied and admired Gustav II Adolf include Napoleon I of France and Carl von Clausewitz. His advancements in military science made Sweden the dominant Baltic power for the next one hundred years (see Swedish Empire). He is also the only Swedish monarch to be styled "the Great". This decision was made by the Swedish Estates of the Realm, when they convened in 1633. Thus, by their decision he is officially, to this day, to be called Gustaf Adolf the Great (Gustavus Adolphus Magnus).

Gustavus Adolphus was the main figure responsible for the success of Swedish arms during the Thirty Years' War and led his nation to great prestige. As a general, Gustavus Adolphus is famous for employing mobile artillery on the battlefield, as well as very aggressive tactics, where attack was stressed over defense, and mobility and cavalry initiative were emphasized.

Among other innovations, he installed an early form of combined arms in his formations, where the cavalry could attack from the safety of an infantry line reinforced by cannon, and retire again within to regroup after their foray. He adopted much shallower infantry formations than were common in the pike and shot armies of the era, with formations typically fighting in 5 or 6 ranks, occasionally supported at some distance by another such formation—the gaps being the provinces of the artillery and cavalry as noted above. His artillery were themselves different—he would not let himself be hindered by cumbersome heavy cannon, but instead over a course of experimentation settled on smaller, more maneuverable weapons, in effect fielding the first light field artillery in history in significant numbers.

These were grouped in batteries supporting his more linearly deployed formations, replacing the cumbersome and unmaneuverable traditional deep squares (such as the Spanish Tercios that were up to 50 ranks deep) used in other pike and shot armies of the day. In consequence, his forces could redeploy and reconfigure very rapidly, confounding his enemies.

His armies were very well trained for the day, so that his musketeers were widely known for their firing accuracy and reload speed: three times faster than any contemporary rivals. Carl von Clausewitz and Napoleon Bonaparte considered him one of the greatest generals of all time; a sentiment agreed with by George S. Patton and others. He was also renowned for the consistency of purpose and the amity of his troops—no one part of his armies was considered better or received preferred treatment, as was common in other armies where the cavalry were the elite, followed by the artillery, and both disdained the lowly infantry. In Gustavus' army the units were extensively cross trained. Both cavalry and infantry could service the artillery, as his heavy cavalry did when turning captured artillery on the opposing Catholic Tercios at First Breitenfeld. Pikemen could shoot—if not as accurately as those designated musketeers—so a valuable firearm could be kept in the firing line. His infantrymen and gunners were taught to ride, if needed. Napoleon thought highly of the achievement, and copied the tactics.
