Greg.... The 13th Kansas was raised as infantry and participated in the Northwest Arkansas campaign in the fall of 1862. They were mustered into service on September 20, 1862 under Colonel Thomas M. Bowen. After the campaign they were marched to Springfield, Missouri from January 1863 until May 19, 1863 when they marched to Fort Scott, Kansas. From June to August 1863 they performed outpost duty at Drywood, Missouri, with part of the regiment being give furlough. (Kansas and Kansans in the Civil War: First through the Thirteenth Volunteer Regiment, Alice L. Fry, pages 81-83)

In W.S. Burke's Official Military History of Kansas Regiments, page 371:

"On the 19th of May it marched for Fort Scott, Kansas, where it arrived on the 29th of the same month, and from thence moved to Drywood, on outpost duty.

The Regiment remained in the vicinity of Fort Scott about two months, during which time most of the men and officers received twenty days furlough. On the 3rd of August the Regiment again took the field with Gen. Blunt, participating in his famous campaign against the rebel Generals Cooper, Cabell, Steele and Stand Waitie, which resulted in driving the enemy to the waters of Red River and the capture of Fort Smith."

Drywood (or Drywood Creek) is several miles east of Fort Scott and one of the main entrance points from Missouri to Fort Scott. The prominance of this area probably resulted from the approach of the Missouri State Guard to Fort Scott in September 1861, which resulted in the battle of Drywood.
