The Indianapolis sent distress calls before sinking. Three stations received the signals; however, none acted upon the call. One commander was drunk, another had ordered his men not to disturb him and a third thought it was a Japanese prank.[10] For a long time the Navy denied that a distress call had been sent. The receipt of the call came to light only after the release of declassified records.

Immediately prior to the attack, the seas had been moderate, the visibility fluctuating but poor in general, and Indianapolis had been steaming at 17 kn (20 mph; 31 km/h). When the ship did not reach Leyte on the 31st, as scheduled, no report was made that she was overdue. This omission was due to a misunderstanding of the Movement Report System. Captain Charles B. McVay III, who had commanded Indianapolis since November 1944, survived the sinking, and was with those rescued days later. In November 1945, he was court-martialed and convicted of "hazarding his ship by failing to zigzag." Several things about the court-martial were controversial. There was evidence that the Navy itself had placed the ship in harm's way, in that McVay's orders were to "zigzag at his discretion, weather permitting." Further, Mochitsura Hashimoto, commander of I-58, testified that zigzagging would have made no difference.

Fleet Admiral Chester Nimitz remitted McVay's sentence and restored him to active duty. McVay retired in 1949. While many of Indianapolis's survivors said McVay was not to blame for the sinking, the families of some of the men who died did ("Merry Christmas! Our family's holiday would be a lot merrier if you hadn't killed my son." - read one piece of hate mail). The guilt that was placed on his shoulders mounted until he committed suicide in 1968, using his Navy-issue revolver. McVay was discovered with a toy sailor in one hand on his front lawn.

In October 2000, the United States Congress passed a resolution that Captain McVay's record should state that "he is exonerated for the loss of Indianapolis." President Bill Clinton signed the resolution. The resolution noted that although several hundred ships of the U.S. Navy were lost in combat in World War II, McVay was the only captain to be court-martialed for the sinking of his ship. In July 2001, the Secretary of the Navy ordered McVay's record cleared of all wrongdoing.
