How To Use This Site


This blog was updated on a daily basis for about two years, with those daily entries ceasing on December 31, 2013. The blog is still active, however, and we hope that people stopping in, who find something lacking, will add to the daily entries.

The blog still receives new posts as well, but now it receives them on items of Wyoming history. That has always been a feature of the blog, but Wyoming's history is rich and there are many items that are not fully covered here, if covered at all. Over time, we hope to remedy that.

You can obtain an entire month's listings by hitting on the appropriate month below, or an individual day by hitting on that calendar date.
Use 2013 for the search date, as that's the day regular dates were established and fixed.

Alternatively, the months are listed immediately below, with the individual days appearing backwards (oldest first).

We hope you enjoy this site.

September 12

1857 U.S. Topographical Engineer Lt. G. K. Warren causes a camp to be erected in the Black Hills. The camp included a stockade and was post was named Camp Jenney.

1911   Edward Conia of Meeteetse received a patent for an animal trap.

 The original structure of the State Mental Hospital in Evanston which was destroyed by a fire on this day in 1917.

1917   The original structure at the Wyoming State Mental Hospital in Evanston was destroyed in a fire.  The large structure was completely destroyed, but no injuries occurred during the fire, although one inmate temporarily escaped.  A new edition built the prior year for male patients was not damaged however.

1918   The 100 Days: The American Army offensive at Saint Mihiel. September 12, 1918.

On this day in 1918 the United States launched its first full scale offensive operation as an American Army.  The U.S. First Army launched the St. Mihiel Offensive.

We've read about this a little bit already, in that the operation was the subject of an argument between Foch and Pershing. As we've noted, in our view, Pershing was wrong and Foch was right. . . the offensive that Pershing was planning had become obsolete.

The offensive that was launched was a compromise plan that Foch could accept and which left the U.S. First Army intact.  It involved an offensive operation in the original direction planned by Pershing but which featured a hard right turn thereafter, incorporating somewhat of the plan envisioned by Foch.  In some ways, the most remarkable aspect of the plan was the commitment to a massive redirection of forces following the offensive to which the Americans committed before it was commenced. The details for that action were the product of of the remarkable mind of George C. Marshall, then a staff officer on Pershing's staff.

On this day the U.S. First Army launched a threefold assault on the remaining part of the St. Mihiel Salient, which the Germans had already begun to plan to withdraw from and which they had in fact commenced to do the day prior to the assault.  The Germans had occupied the area since 1914 and had densely prepared defensive positions.  Attached to the U.S. Army were four French divisions in addition to fourteen American divisions. The US alone committed 550,000 men to the assault with the French contributing another 110,000. The Germans, who had already committed to withdraw from the salient, numbered only about 50,000 men in ten divisions, about half of whom would become causalities in the attack.

Air support for the assault was massive, with 1,481 aircraft committed to it, about 40% of which were piloted by American airmen.  The remainder were British, French and Italian.



The assault, in part because of the massive disproportionate nature of the contesting forces, and in part because it caught the German army in the midst of a withdrawal, was instantly successful and exceeded expectations.  Having said that, the operation was also a well planned combined arms attack and it featured the highly aggressive nature of American arms in the war which was shocking at the time.  Objectives were achieved within the first two days at which it was halted in anticipation of the planned offensive at the Meuse Argonne.
The battle was the first one in which American forces fought in an American Army, rather than associated with an army of the other allies.
