did not lead his army into any after Nördlingen. Unwilling to risk his army in pitched battle, he still could not prevent the ruin of his armies in various campaigns because of lack of supplies. In fact, Gallas often complained about the unsustainable conditions but still obediently followed the orders of the emperor. After his disastrous campaigns of 1638 and 1644, he became even known as the “destroyer of armies” - originating from French and Swedish war propaganda, it evolved into a lasting nickname. According to his biographer Rebitsch, Gallas was an able and wily tactician who most excelled in the defence but often lacked the determination and risk appetite in the offensive. He was competent in the operative planning of his campaigns but more and more overstrained in their execution under the increasingly difficult external conditions of the later Thirty Years' War. Gallas was in contrast to for example Torstensson or Piccolomini not among the commanders that could adequately adapt to these altered conditions. Gallas was most likely an alcoholic like many of his contemporaries in the military, for example his Swedish opponent Johan Banér. Yet authentic descriptions of his drinking behaviour are rather rare and derive mostly from internal rivals like Charles of Lorraine in 1635 or Archduke Leopold Wilhelm in 1645. Family Gallas first married Isabella of Arco in 1630 in a double marriage with his colleague Johann von Aldringen who married Isabella's sister Livia. After the death of his first wife in 1632, Gallas remarried Dorothea Anna von Lodron two years later, a daughter of Count Philipp von Lodron and relative to Salzburg's Prince-Bishop Paris von Lodron. Together, they had at least seven children, of which Franz Ferdinand (1635–1697), Theresia Annunziata Francesca († 1667), Anton Pankraz (1638–1695) and Maria Viktoria (1639–1687) survived their childhood. The most remarkable descendant of Gallas was his grandson Johann Wenzel von Gallas (1669–1719), a diplomat and Austrian Viceroy of Naples. After the death of the last male Gallas in 1757, Johann Wenzel's son Philipp Josef, the heir Christian Philipp von Clam took the name Clam-Gallas, a family which provided many reputable soldiers to the Imperial army. Possessions Despite holding the title Count of Campo, Gallas never possessed the eponymous Castle Campo near Fiavé that his family had lost many generations before. From his pay as soldier and officer, he purchased the first pieces of land prior to 1621, followed by a
