During the dreary winter at Valley Forge, Washington busied himself in improving the organization of his army. The fall of the Conway cabal removed many obstacles. Greene was persuaded, somewhat against his wishes, to serve as quartermaster-general, and forthwith the duties of that important office were discharged with zeal and promptness. Conway's resignation opened the way for a most auspicious change in the inspectorship of the army. Of all the foreign officers who served under Washington during the War for Independence, the Baron von Steuben was in many respects the most important. Member of a noble family which for five centuries had been distinguished in the local annals of Magdeburg, Steuben was one of the best educated and most experienced soldiers of Germany. His grandfather, an able theologian, was well known as the author of a critical treatise on the New Testament. His uncle, an eminent mathematician, had been the inventor of a new system of fortification. His father had seen half a century of honourable service in the corps of engineers. He had himself held the rank of first lieutenant at the beginning of the Seven Years' War, and after excellent service in the battles of Prague, Rossbach, and Kunersdorf he was raised to a position on the staff of Frederick the Great. At the end of the war, when the thrifty king reduced his army, and Blücher with other officers afterward famous left the service, Steuben retired to private life, with the honorary rank of General of the Circle of Swabia. For more than ten years he was grand marshal to the Prince of Hohenzollern-Hechingen. Then he went travelling about Europe, until in the spring of 1777 he arrived in Paris, and became acquainted with Franklin and Beaumarchais. [Portrait: Steuben] [Portrait: Frederic] The American alliance was already secretly contemplated by the French ministry, and the astute Vergennes, knowing that the chief defect of our armies lay in their want of organization and discipline, saw in the scientific German soldier an efficient instrument for remedying the evil. After much hesitation Steuben was persuaded to undertake the task. That his arrival upon the scene might excite no heart-burning among the American officers, the honorary rank which he held in Germany was translated by Vergennes into the rank of lieutenant-general, which the Americans would at once recognize as more eminent than any position existing in their own army except that of the commander-in-chief.
