In the meantime, MacArthur's amphibious assault at Inchon went ahead on 15 September. "The success of Inchon was so great and the subsequent prestige of General MacArthur was so overpowering," Collins later recalled, "that the Chiefs hesitated thereafter to question later plans and decisions of the general, which should have been challenged." In response to a rumor that the Eighth Army planned to halt at the 38th parallel and await United Nations authorization to cross, Marshall sent a message to MacArthur informing him that: "We want you to feel unhampered tactically and strategically to proceed north of 38th parallel. Announcement above referred to may precipitate embarrassment in the UN where evident desire is not to be confronted with necessity of a vote on passage, rather to find you have found it militarily necessary to do so." A few days later, MacArthur was instructed not to issue an announcement that his forces had crossed the 38th parallel. On 7 October a United Nations General Assembly Resolution was passed that could be broadly construed as permitting the invasion of North Korea.
