The reasoning was twofold: to prevent <a href=\"https:\/\/www.smithsonianmag.com\/history\/world-war-ii-rumor-clinics-helped-america-battle-wild-gossip-180983883\/\">widespread panic<\/a> among the American public and to avoid informing the Germans just how destructive their campaign was.

This number\u2014low when compared with better-known battles like D-Day, which had a single-day death toll of <a href=\"https:\/\/apnews.com\/article\/d-day-invasion-normandy-france-nazis-07094640dd7bb938a23e144cc23f348c\">4,414 Allied troops<\/a>\u2014is likely part of the reason the attacks haven\u2019t gained as much recognition. \u201cThe story remains sort of remote, and that\u2019s because of the way people consume World War II history,\u201d Morgan says. \u201cThey only want to consume the most famous or infamous parts of that history.\u201d<\/p>\n<p>The historical importance of the Gulf campaign, Morgan adds, comes down to the value of the resources lost when the Allied vessels sank.
