Always glad to help. The US coast artillery is a particular interest of mineand I have collected a good deal of reference material.

Hi agian,

Is this photocaption correct? 12in M1895 Fort Mills

I am afraid that the caption on the photo is in error but the title on the file is correct. The gun is a 10 inch M1895 mI on a carriage dissappearing LF M1901. The identifying points are the ladder shape of the Front sighting platform support and the square not round appearance of the sighting standard, circled on picures. The ladder is not present and the sighting standard is round in shape. See pic no 3. As all 12 inch DC on corregidor were mounted on 12 inch M1901 Carriages this must be a 10 inch.

[ROLAND1369]

A 10 inch would mean this is from Battery Warwick Fort Mills or Battery Warwick on Fort Wint, Subic Bay. An additional recognition point is the lack of a hole in the rounded reinforcement plate in front of the circled front support. This hole is present in the 12 inch M1901.

Upon reexamining my previous post my limited knowledge greatly exceeded my ability to compose an answer. As it is impossible for Battery Warwick to be emplaced in two places at once it should be corrected to read that the 10 inch battery on Fort Mills was Battery Grubbs.

Thanj you very much for your help, again, ROLAND1369 .

10in M1895 on a carriage dissappearing LF M1901 of Battery Grubbs, therefore.

Which is the best book to differentiate the various models of US coastal guns and mounts?

If you want one book which will give you a complete overview of the US coast Artillery including guns, fire control, mines, forts, and general history go with"American Seacoast Defenses, a Reference guide. 2nd edition" Mark Berhow, CDSG Press, 2004. ISBN 0-9748167-0-1

Thank you ROLAND1369.

I found this image on the net (I do not remember the exact website).
According to photocaption Battery West, Corregidor

Any idea about the gun?

[ROLAND1369]

This is the top carriage of a 155 mm m1918 GPF which has been dismounted from the wheels and trails and mounted on a fixed concrete emplacement. It was named Battery Monja and was later casemated. Note the breech closing mechanism and stepped barrel.

Hi all,

A nice image of a 406mm 16in Mk.II naval gun (I think):

Any documentation, other than firing tables, that would indicate how accurate the coastal artillery was vs moving ships?

Also any documentation from tests indicating their actual ammunition effects on armored targets? There is some of both in the FA Journal of the 1920s, but of course nothing for the CA.

[ROLAND1369]

In partial answer to your question, the Coast artillery Service Practices were conducted against moving towed targets. The closest documention on accuracy is the enclosed table which shows the probible error of the weapons systems stripped of all nonstandard errrors, ie human, Powder pressure variance, nonstandard weight projectile, projectile failure(manufacture loss of rotating band). I have only the 1911 and 1912 results and the scoring includes more than simple accuracy. Table is from TM 4-235 Coast Artillery Target Practice Feb 27 1941.

Forgot to add table is in yards.
