Three different views regarding the source of the war power found expression in the early years of the Constitution and continued to vie for supremacy for nearly a century and a half. Writing in The Federalist,[1203] Hamilton elaborated the theory that the war power is an aggregate of the particular powers granted by article I, section 8. Not many years later, in 1795, the argument was advanced that the war power of the National Government is an attribute of sovereignty and hence not dependent upon the affirmative grants of the written Constitution.[1204] Chief Justice Marshall appears to have taken a still different view, namely that the power to wage war is implied from the power to declare it. In McCulloch _v._ Maryland[1205] he listed the power "to declare _and conduct_ a war"[1206] as one of the "enumerated powers" from which the authority to charter the Bank of the United States was deduced. During the era of the Civil War the two latter theories were both given countenance by the Supreme Court. Speaking for four Justices in Ex Parte Milligan, Chief Justice Chase described the power to declare war as "necessarily" extending "to all legislation essential to the prosecution of war with vigor and success, except such as interferes with the command of the forces and conduct of campaigns."[1207] In another case, adopting the terminology used by Lincoln in his Message to Congress on July 4, 1861,[1208] the Court referred to "the war power" as a single unified power.[1209]
Thereafter we find the phrase, "the war power," being used by both Chief Justice White[1210] and Chief Justice Hughes,[1211] the former declaring the power to be "complete and undivided."[1212] Not until 1936 however did the Court explain the logical basis for imputing such an inherent power to the Federal Government. In United States _v._ Curtiss-Wright Export Corp.,[1213] the reasons for this conclusion were stated by Justice Sutherland as follows: "As a result of the separation from Great Britain by the colonies acting as a unit, the powers of external sovereignty passed from the Crown not to the colonies severally, but to the colonies in their collective and corporate capacity as the United States of America. Even before the Declaration, the colonies were a unit in foreign affairs, acting through a common agency--namely the Continental Congress, composed of delegates from the thirteen colonies. That agency exercised the powers of war and peace, raised an army, created a navy, and finally adopted the Declaration of Independence. * * * It results that the investment of the Federal Government with the powers of external sovereignty did not depend upon the affirmative grants of the Constitution. The power to declare and wage war, to conclude peace, to make treaties, to maintain diplomatic relations with other sovereignties, if they had never been mentioned in the Constitution, would have vested in the Federal Government as necessary concomitants of nationality."[1214]
