What did the declassified documents reveal?

Welcome to Declassified. Today, we examine a declassified C-I-A intelligence summary concerning Soviet logistics support for North Korea, China, and Japan in the early days of the Korean War. This record, dated approximately July twenty-seventh, nineteen-fifty, provides a snapshot of U.S. intelligence assessments during a critical period. You can find this document at archive.org, under the heading U-S Intelligence on China C-I-zero-zero-four-zero-six. This document was declassified and approved for release on March twenty-fourth, two-thousand-ten, under a Freedom of Information Act review. Its release sheds light on the types of intelligence collected by the United States at the outset of the Korean conflict. The document reads: Logistics support by the U-S-S-R for North Korean operations has continued beyond June twenty-fifth, nineteen-fifty. During the first ten days of July, fragmentary coverage reveals that one-hundred-thirty-two tons of materials had been shipped into Korea from the U-S-S-R and that three-thousand-two-hundred-thirteen metric tons of materials, including vehicles, tires, raw materials, and special clothing, were on hand awaiting shipment as of July tenth at Touen and Antung. Soviet exports to China in May and June, with shipments continuing through August, include substantial quantities of petroleum products and vehicles, one-thousand-three-hundred at least. Receipt of these items, believed to be only a part of the total called for in Soviet-Chinese trade agreements, will increase the military potential of Chinese Communist Armed Forces. The impression gained, particularly in the case of supplies shipments, is that these supplies are considerably in excess of present requirements of either the Chinese or Korean Communist forces and may be primarily for use by Soviet forces in North China. New information now assigns a total of twelve tactical divisions, one-hundred-twenty-thousand men, to the North Korean Armed Forces, an increase of three divisions and twenty-thousand men over previous estimates. Some of these additional forces may be drawn from Koreans in the U-S-S-R and in Chinese Communist Armies. The Soviet attitude towards Japan may be indicated by an article in the official Soviet Army journal charging "de facto" participation by Japan in operations against North Korea. No official contextual statement accompanies this declassified intelligence summary. The document stands as a direct record of U.S. intelligence analysis at the time. This is what the public record looks like at its most ordinary. storyflo.com, and the document's canonical U-R-L: archive.org/download/us-china-intel-C-I-zero-zero-four-zero-six/C-I-zero-zero-four-zero-sixdjvu.txt
