Marigold was an American codename for a failed secret attempt to reach a compromise solution to the Vietnam War that was carried out by the Polish diplomat Janusz Lewandowski, a member of the International Control Commission, and the Italian ambassador in Saigon, Giovanni D'Orlandi, in collaboration with the US ambassador in Saigon, Henry Cabot Lodge Jr., in late 1966.
[1][2][3] In his 2012 book, James Hershberg argues that had not the United States missed the opportunity, direct talks between the United States and North Vietnam could have begun roughly a year and a half before May 1968, when they actually occurred in Paris; the war or at least the massive US direct military involvement in it might have ended sooner; and the number of Americans who perished in the war might not have escalated from 6,250 to over 58,000.
US President Lyndon Johnson had authorized the continued strikes despite warnings from the Poles and then from senior members of his own national security team that any further attacks on Hanoi might cause Marigold to collapse.
Polish Foreign Minister Adam Rapacki relayed Hanoi's final rejection to Gronouski on December 30, and Marigold was dead.

Estabrook in The Washington Post in February 1967, and was then the subject of an intense investigation by Los Angeles Times reporters David Kraslow and Stuart H. Loory, who published their findings in The Secret Search for Peace in Vietnam (New York: Random House, 1968).
