One of my favorite aspects of military history is the availability of documentation.

Militaries are big things, indeed. They have lots of soldiers, lots of vehicles, and lots weapons that vary in size and lethality. They also have support staff, logistical supply chains, doctors, nurses, engineers, ditch diggers, builders, movers, doers, and even dreamers. They are everything a human being needs to be trained and housed and fed and dressed and armed and cared for while in the States, as well as everything needed to ship that person across an ocean and then train, house, feed, dress, arm, and care for that person while on deployment. And that’s just the Army.

In order to make such a large, complicated entity that culturally thrives on exactitude run like clockwork, militaries in general and Navies in particular require a great deal of data collection and record keeping. Today that burden is eased thanks to computers and smart devices, but back during World War II those processes requires lots of paper, pencils, typewriters, and people to jot down all those things that needed to be jotted down.

Deck logs were indispensable record-keeping devices for ships. They recorded all sorts of things, from the windspeed at different times of day to the ship’s location and speed. They also contained a narrative of the day’s events. Most of these were mundane – who boarded and left the ship, details about food and fuel deliveries, inspection reports, etc.

The food deliveries are especially interesting, since they give us a sense what (and how much) all those sailors ate (they sure loved their potatoes):

The logs provide additional threads to pull, which reveal about not only the ship and its crew, but the wider community that surrounded and interacted with them. For instance, the Chun Hoon Company supplied many of the ship’s vegetables and fruits. The company’s namesake founder immigrated to Oahu in 1887 at the age of 14, and after starting out as a vegetable peddler Chun Hoon became increasingly successful as a vendor and then later as a grocer. Although he passed away in 1935 his sons took over the business, and in 1939 they opened a brand new supermarket at the corner of Nuuanu and School Streets in Honolulu. By 1940 the Chun Hoon Company was a major player in local business and a substantial benefactor for several local schools and charities.

More broadly, Chinese-Americans found and took advantage of the opportunities they found in Hawaii, which offered a space of relative refuge from persecution when compared to the post-Chinese Exclusion Act United States mainland. Of course, Hawaii itself was not annexed by the United States until 1898, by which time nearly 50,000 Chinese immigrants had relocated to Oahu. But by that time, Chinese-Hawaiians were already well-integrated into the island’s economy, and immigrants like Chun Hoon continued to thrive despite the changing of the flag. His company was an institution by 1940, and while the Chew and the United States Navy were important customers for the business, they were by no means the only ones.

I had no idea about the Chun Hoon Company before looking at this specific page in the Deck Log. I have several hundred more pages to go. What other secrets do they hold? What other connections do they suggest? What was the weather like at 7:30am on December 7th, 1941? Where was the ship located the next morning at 9am? Deck Logs can help us answer these questions and more . . .

To find Deck Logs for other ships, you will need to do one of two things: you can go directly to the Archives II NARA reading room in College Park, Maryland and request them, or you can hire an independent researcher in the area to scan the ones you want. You will have to wait until NARA facilities reopen after the COVID quarantines lift, and once that happens there will likely be a considerable backlog of folks like me who are clamoring to begin or continue ongoing research projects. But the staff there is very helpful, and the materials themselves are easy to access.
