The keyword Austria indicates that this has nine lines, and is to be read<br />
U1, D6, U2, D3, U5, D4. The only codeword in this message is “Camden,”<br />
Major General G. H. Thomas. By this time <strong>St</strong>ager had regularized the<br />
location <strong>of</strong> the blind words: always insert one at the end <strong>of</strong> a column being<br />

12. [Antonucci] <strong>St</strong>ager’s Cipher No. 12 was used from September 1862 until<br />
August 1864. It had many code words, for times <strong>of</strong> days, prominent<br />
<strong>of</strong>ficers, place names, and even commonly used words and phrases. For<br />
example, in the following message Arabia is Major General Don Carlos<br />
Buell, Adam is Major General Henry Halleck, and Lincoln is Louisville,<br />

years most messages to Washington were sent to his name. Likewise, Drake must be the<br />
telegraph operator stationed with the commander the message is for, Major General D.C.<br />
Buell in this case.
