One of our original projects was to create a searchable database with information, maps, and pictures of the various locations that had defense structures. Sadly, that project never really got started. But, we have made some strides in collecting source information on the structures built for harbor defense. The CDSG now has digitized a fairly complete set of Engineer documents on the harbor defense structures of the United States Army. The data sets available have been broken down by the various harbor defenses in the list below so you can order sets of records by coast/harbor defense, or get the complete collection. This is a very good collection of historical information on the harbor defense structures: batteries, fire control, mine support, searchlights, etc., built at the various harbor locations.

---> Contact Mark Berhow by post/email if you are interested in ordering only specific titles <---The CDSG ePress has announced that the third edition of American Seacoast Defenses, a Reference Guide (ASD3) is now available as electronic PDF document. The third edition features updated and enhanced photographs throughout the book, with an extensive revision of the uniforms and insignia sections. This makes it great for searching and viewing sections with a great zoom for looking at details, especially on the new pad portable readers. Pages or sections can be printed as needed. The file format is PDF, not an ePub format, so a reader that is compatible with adobe acrobat is required.
The CDSG ePress is offering this electronic version for $40, the same price as the hard copy, less shipping. To order please contact Mark Berhow at berhowma@comcast.net or send a check or money order to him. Once he receives your order he will send you the file electronically by FTP transfer.

Reports of completed batteries (RCBs) and reports of completed works (RCWs) were forms used by the Corps of Engineers to document seacoast fortifications and other structures related to coast defense. RCBs were in use from 1900 until 1919. RCWs were in use from 1919 until the coast artillery was disbanded in 1950. Both are essential documents in the study of modern U.S. coast defenses, 1890-1950.
From 1903 to 1919 the RCB was used to compile information on the batteries located at specific harbor defenses, including the official name of each batteries, the individual number and name of the manufacturer of each gun or mortar and carriage with the number of the emplacement each gun or mortar and carriage was mounted in. RCBs were submitted annually.
Reports of completed works (RCWs) were a new set of forms that superceded the RCBs in 1919. It prescribed that all data in the RCBs would be submitted on seven forms referred to as reports of completed works. Furthermore, new forms need only be submitted whenever changes in works made the old forms obsolete, compared to the annual submission of RCBs. The seven forms were:
Form 1 all important data relating to an individual battery
Form 2 details of fire control and torpedo structures
Form 3 details of mine wharfs and tramways
Form 4 details of searchlights (a separate sheet for each light)
Form 5 details of electric plants
Form 6 existing Engineer Dept structures of permanent or semi-permanent nature
Form 7 a blueprint of the battery
The big scanning project of all of the coast artillery RCBs and RCWs is now complete. A first generation copy set of over 12,000 pages--- nearly all the RCBs and RCWs available at NARA II--- have been scanned and digitized as PDF pages. This will be the most extensive collection of RCBs and RCWs available. The documents are organized by harbor defense and broken down into two or more files by harbor (RCBs) and fort/location (RCWs) depending on the number of pages. Each document contains a series of grey-scale images of each of the RCB/RCW forms in the collection related to each harbor defense. Grey scale was chosen because black and white scans could not sufficiently resolve the "negative" forms and give a legible printout. The grey scale scans are at 200 dpi, which gives a bigger file size than black and white but with sufficient resolution to make a readable copy. The PDF documents are essentially a series of electronic photocopies, and as such the files are NOT text searchable, so a researcher will have to scroll through each file to find the pages of interest. The RCB collection has been added to each harbor defense collection.
Total: 120 files, 12,000 plus pages, 28 GB, 6 DVDs
The engineer assigned to each harbor defense kept a notebook on the defense structures that were located in a given harbor defense. They maintained a ledger, a journal, and memorandum log for the batteries, the fire control structures, the electrical generators, the searchlights, the torpedo (mine) structures, and in some cases, the land defenses. A fairly complete set appears to have been collected around the mid-1920s and is now housed in the National Archives. These have been copies and scanned as PDFs. These notebooks have information on when the structures were built, but more importantly information on modifications and changes to these structures over the years, for instance, we can see what guns were removed from what battery during 1917-18. The notes show that both Los Angeles, CA, and Guantanimo Bay, Cuba, had a complete set of structures built for the control of mine fields, even though the mines were not deployed at these locations. These are a great source of additional information on the Endicott and Taft era fortifications.
Total: 30 files, 2600 pages, 2.63 GB, 1 DVD
A Harbor Defense Project was a written document setting forth the missions of the harbor defense, the means to be employed, the methods to be followed, and the successive steps to be taken to accomplish the mission, based not only upon the means actually available or definitely allocated, but also upon those not in existence that were deemed necessary or desirable. When approved by the secretary of war, the project was the official statement of the resources approved for the harbor defense, both present and projected. These projects were relatively brief, typically less than 20 pages. For the continental defenses, projects were completed in 1932/33, 1937, and 1943-46; for Alaska, in 1942; and for the Panama Canal Zone in 1946. The specific details were contained in the annexes prepared by the local harbor defense. The last series of these were termed Supplements, but contained the same series of annexes. These annexes/supplements furnished a concise record of the status both of existing harbor defense fortification construction and equipment, and of new or modified construction which has been approved by the War Department for future accomplishment, and made available information of a technical and tactical nature which is not otherwise available in usable form. They were in the range of one or two hundred pages. Not surprisingly, the larger harbor defenses tended to have the larger annexes.
Annex A - Armament
Annex B - Fire Control
Annex C - Seacoast Searchlights
Annex D - Underwater Defense
Annex E - Anti-Aircraft Artillery (Harbor Defense)
Annex F - Gas Defense
Annex G - Equipment
Annex H - Real Estate Required
The scans of these annexes are B&W at 300 dpi. While the original documents in the National Archives were legal-size, some were photocopied that size and some letter-size. The price is $10 for a CD with the entire collection.
Total: 25 files, 4016 pages, 300 MB, 1 CD
No complete projects or annexes have been located for Oahu or the Philippine Islands.
The Quartermaster Corps kept careful historical records on the buildings and structures for which it was responsible. These records were transferred to the Corps of Engineers along with the responsibility for construction and maintenance. The Historical Record of Buildings described individual structures. The term building was used in the broadest sense, and included wharfs, manure pits, tennis courts, and even statues. The first such forms in the record, dating from 1905, are un-numbered. They contain information on two buildings, one on each side of the 10 x 12 card-stock form. Filed by post building number, the forms list the construction date, materials, and equipment (to include wash basins, showers, urinals, screen doors, and wall lockers), as well as an annual list of expenditures for repairs. Perhaps most valuable, the forms normally displayed a 4 x 5-inch black and white photograph of the structure. By 1921, the forms, now 173A, were enlarged to 10 x 14 inches and covered only one structure. On the reverse a grid pattern was provided for a simple plan of the structure. Plans were drawn for some structures; others had blueprints pasted on, while still others were blank. In 1924, the form was renumbered 117, but otherwise remained relatively unchanged. These forms cover buildings built until the Corps of Engineers assumed responsibility days before the United States entered World War II. Both permanent and temporary buildings are included, as well as a number of civilian structures taken over by the army when the land on which they stood became part of a military post.
One of the most important entries on the Historical Record of Buildings was the OQMG (Office of the Quartermaster General) plan number, which was normally listed, at least for 1891-1917 buildings. These plan numbers, in turn, lead to another valuable source. From 1891 through 1917, the quartermasters built most structures to numbered standard plans. As these plans were updated, letter suffixes were added. The Cartographic Branch at Archives II contains Standard Plans of Army Post Buildings (Received from Quartermaster Office) 1891-1917. These are hundreds of standard plans prepared by the Office of the Quartermaster General. A notebook lists the plans by number and suffix, with the number of sheets prepared. To request them, merely specify RG 77, PI NM-19, Standard Plans of Army Post Buildings 1891-1917, with the plan number and letter suffix desired.
See article by Bolling Smith in the Coast Defense Journal Vol. 16, No. 2 pp. 29-42, for more details.
The CDSG ePress has scanned in a fairly complete set of these records for all the coast artillery posts circa 1905-1940.
A number of aerial photographs of the various harbor defense installations were taken by the Signal Corps from 1920s to the beginning of World War II. This collection of photographic prints has been scanned and are now available as part of the CDSG offerings on harbor defenses. The collection includes photo sets of the following defenses: Baltimore (16 photos), Boston (74 photos), Canal Zone (29 photos), Charleston (14 photos), Chesapeake Bay (60 photos), Delaware Bay (21 photos), Eastern New York (28 photos), Galveston (3 photos), The Great Lakes (12 photos), Key West (4 photos), Long Island Sound (37 photos), Los Angeles (7 photos), Narragansett Bay (16 photos), NE Florida (4 photos), Oahu (53 photos), Potomac River (20 photos), Pensacola (7 photos), The Phillipines (30 photos), Portland (29 photos), Puget Sound (9 photos), San Diego (7 photos), San Francisco (38 photos), Sandy Hook & Rockaway (12 photos), Savannah (11 photos), Southern New York (75 photos), and a series of photos taken for the Western Defense Command (San Diego (2 photos), Los Angeles (5 photos), San Francisco (56 photos), Columbia River (36 photos), Puget Sound (85 photos). Each set has anywhere from a few shots to over a dozen shots of the various forts. A great collection for those interested in seeing what was at a fort in the past. The collection is available in high resolution TIFs (36.57 GB fits on 9 DVDs) of compressed JPGs (7.64 GB, fits on 2 DVDs). Contact Mark Berhow (berhowma@comcast.net) for information on ordering or if you want to only get only specific sets.

Several Army documents have been scanned and placed on line as downloadable PDF files.
For example: Survey of Japanese Seacoast Artillery, 1946 by GHQ USAFPAC, Seacoast Artillery Board 160pp. The US Army Military History Institute has placed this valuable and rare document on the web in pdf format, which will allow it to be viewed using the free Adobe Reader. This report by a board of coast artillery officers at the end of the war focuses primarily on the seacoast defenses of the Japanese home islands. It is a very detailed report, with much information not available elsewhere. It is divided in three parts. Parts One and Two cover Japanese army and navy seacoast artillery. Part Three deals with controlled submarine mines. All three sections cover the training, organization, and equipment of these various groups. Tables detail the characteristics of Japanese army and navy seacoast weapons and ammunition, while photos, drawings, and plans illustrate many of the weapons, including the big 41 cm turrets. Maps show the locations of Japanese batteries in the home islands with their fields of fire, and the text provides detailed information on Japanese fire control equipment and methods. Part Three is a detailed look at Japanese controlled mines, including magnetic and acoustic detection equipment.

Seacoast Fortifications Preservation Manual addresses the extensive and nationally significant seacoast fortification network in Golden Gate National Recreation Area. Its purpose is to identify specific preservation issues affecting the fortifications; provide technical information about appropriate treatments; and develop a methodology for prioritizing the application of those treatments to the park's extensive fortification network. Written by a team of five preservation specialists, the manual is organized as sections that discuss the historic significance and preservation rationale for the resource; explain the physical history of the fortifications in order to better understand their evolving nature; and present up-to-date and practical treatment solutions for the many preservation challenges that these fortifications present.
