Intelligence Gathering in War
Since the Revolutionary War era, American political and military leaders have recognized the value of gathering intelligence on their adversaries, especially in wartime. Early attempts to collect intelligence in wartime were typically small, ad hoc efforts that ended quickly once peace returned. They emphasized the use of spies to secretly acquire information that contributed to success in battle. Such information included knowledge of the enemy's strengths, weaknesses, intentions, and dispositions. Beginning in the late 19th century with the creation and growth of permanent intelligence organizations, the collection of intelligence was no longer limited to wartime. In peacetime, American intelligence gathering became a longterm effort to collect information from open and clandestine sources to aid government policy makers and avert strategic surprise. The intelligence gathered included information about the intentions and capabilities of potential foreign adversaries and, occasionally, data on U.S. citizens and groups deemed to be subversive.
The development of several new technologies shifted the focus of American intelligence gathering from human to technological sources. The introduction of new means of communication, such as the telegraph, radio, and telephone, expanded the flow of information, giving intelligence agencies more opportunities to intercept and read messages of interest. Increasingly sophisticated cameras and other imaging technology, mounted first on airplanes and later on satellites, also enabled intelligence organizations to gather extremely accurate information from great distances. The growth of peacetime intelligence activities and the increased emphasis on technical collection methods generated and continue to generate debates about the effectiveness of American intelligence gathering and its compatibility with democracy.
The American Revolution
Intelligence gathering played an important role in the American Revolution. Gen. George Washington listed gaining more information about British forces as one of his most important duties when he assumed command of the Continental Army in July 1775. Washington established a network of spies to monitor British movements and intentions. Using a variety of cover stories, Washington's agents moved freely in and out of British-controlled Philadelphia and New York, carrying intelligence on British troops, fortifications, supplies, and plans.
The primary source of intelligence from abroad during the Revolution was the Committee of Secret Correspondence, established by the Continental Congress on November 29, 1775. The committee's members acquired foreign publications, hired spies, and funded propaganda activities to both discover and influence the attitudes of foreign powers about the American cause. Many of the committee's activities were cloaked in secrecy. It used codes, ciphers, and invisible inks to communicate with its agents and kept secret their names and those of its correspondents.
After the American Revolution ended, the systems created for gathering intelligence were disbanded. Intelligence collection became the responsibility of the president, who dispatched military observers or special agents to gather specific information when necessary. At the request of President Washington, Congress established the Contingent Fund for Foreign Intercourse, often called the secret service fund, in 1790. The president had to certify the sums spent from the fund but could conceal the purposes and recipients. The creation of the fund reinforced the belief that the government could legitimately withhold information related to intelligence gathering from both Congress and the American public. Within three years, the size of the fund increased to $1 million, 12 percent of federal budget. Initially, the money was used largely to ransom American hostages held in Algiers and pay off foreign officials. The size of the contingent fund varied over the next several decades, but the belief that intelligence gathering should be kept secret remained constant. When the House of Representatives asked Pres. James K. Polk to surrender the accounts of all payments from the fund during the previous administration, Polk refused. He explained that in wartime or when war was imminent, employing individuals to collect information was often necessary. Such individuals, generally, could obtain information successfully only if secrecy was guaranteed.
