I have a map of the raid, signed by a handful of Raiders, that was given to my grandfather aboard the Hornet shortly before they launched.
That is very cool. What a piece of history!
There are moments in war where a propaganda victory outweighs any tactical calculation or effect and the Doolittle Raid was perhaps the biggest example.
It was a huge blow to the psyche of Japan and the psychological damage (and boost to the US) did far more than a thousand times the tonnage of mobs could have.
Japan had to commit war machinery to the home islands as a result.
Said to advance Japan’s plans to become embroiled in the Battle of Midway, with results favorable to US and Allies.
Of the captured airmen, 4 became POWs, another 4 died in captivity, and three were executed.

More properly, this was a Publicity Victory, there was no Propaganda involved, only Factual Events.
