What you do is this:
Scan your document as separate pages.
Go to this web site: http://finereader.ab.../en/Task/Queue/
Select a page or pages on your computer using the 'Upload' button
Click on 'Click here if your text is set in a black-letter typeface'
and select 'German'
from the drop down list.
Select your preferred output file format
Click on 'Recognise'
The site will then convert the page of Fraktur typeface into a page of modern German type which you can download and open in your word processor. You get 20 free page conversions. Your other 37 pages will cost you £3 (with 13 conversions left over for another topic).
Then open up one of the many on-line machine translation sites. I suggest one of them should be IMTranslator.net as this simultaneously provides the results from Babylon, Promt, Google and Microsoft (others are Yahoo/Babel Fish, Worldlingo, Reverso and SDL Freen Translation). Copy and past your document in sections (several have character limits for how much can be translated in one go) and then, if you have any knowledge of the subject, you should be able to convert the results into something sensible/readable. I cannot read German but have translated 150+ pages of regimental histories, etc. quite happily using this method.
A couple of useful books will be: a good German-English dictionary (I use Collins) and German Military Terms 1918 published by the Imperial War Museum which gives the translations for German military words/phrases as well as full details of abbreviations and acronyms.
