Which president was given up for lost when the navy boat was sliced through by an enemy ship?

The president in question is Franklin D. Roosevelt. During World War II, a naval incident involving the USS Indianapolis, which was torpedoed by a Japanese submarine in July 1945, led to significant speculation and concern about his safety and leadership. However, Roosevelt was not on the ship; he was in Washington, D.C., at the time. The confusion often arises due to the dramatic nature of wartime events and the challenges faced by leaders during such crises.
