Crawford was born in Lawrence County, Indiana and grew up on a farm while he attended school in Bedford, Indiana. He later attended law school at Cincinnati College. His parents were William and Jane Crawford, who were natives of North Carolina and had moved to Indiana Territory in 1815. His paternal grandparents were James and Mary Crawford, his grandfather having been a Revolutionary soldier.
Arrival in Kansas
Samuel J. Crawford arrived in Kansas Territory and began the practice of law at Garnett, Kansas on March 1, 1859. In May of the same year of his arrival he attended the Osawatomie Convention and participated in the organization of the Republican Party in Kansas. In September of the same year he was a delegate to the Republican state convention at Topeka, which placed in nomination state officers under the Wyandotte Constitution. In November 1859, he was elected a member of the first state Legislature, and assisted in putting the state government into operation.
Military career
Toward the close of the first session the country was involved in war. He resigned his legislative seat to become captain in the 2nd Kansas Infantry. He participated in the 1861 Southwest Missouri campaign led by General Lyon, and took part in all the engagements, including the crucial Battle of Wilson's Creek. In March 1862, Crawford was assigned command of Company A, 2nd Kansas Cavalry, and later commanded of a battalion in the same regiment. With the 2nd Kansas Cavalry he was with General James G. Blunt in Southwest Missouri, Arkansas, and Indian Territory until early in the fall of 1862. During that time he participated in the battles of Newtonia, Old Fort Wayne, Cane Hill, Bald Peak, Cove Creek, Prairie Grove and Van Buren. At Old Fort Wayne he led his battalion in the charge which resulted in the capture of an entire battery of artillery. On March 12, 1863, he was assigned command of the 2nd Kansas Cavalry and soon afterward joined Blunt at Fort Gibson for an expedition south through the Choctaw Nation. This campaign ended with the taking of Fort Smith, Arkansas and Colonel Crawford was instrumental in capturing a number of prisoners, wagons, horses, a Confederate paymaster and $40,000 of Confederate money. In November 1863, he was appointed colonel of the 2nd Kansas Infantry. His regiment participated in the Camden Expedition and performed admirably in the Battle of Jenkins' Ferry where it relieved an Indiana regiment and captured a rebel artillery battery consisting of three guns. In March 1864, he joined General Frederick Steele on an expedition to the Red River under the general command of General Nathaniel Banks. At Jenkins Ferry his command lost heavily and his own horse was shot.
After retiring from the governorship Crawford was in the real estate business at Emporia, Kansas until 1876, when he moved to Topeka to undertake the prosecution of certain claims against the United States for indemnity school lands, and in this he rendered much aid to Kansas. Subsequently, he moved to Washington, DC, and practiced law there for a number of years. Among other activities Crawford published Kansas in the '60s, a work which attracted much attention as a picture of conditions in early Kansas history. On December 1, 1870 he formed the Florence Town Company. It was a group of men who learned of the proposed route of the Atchison, Topeka and Santa Fe Railway who decided on a town site where the railroad would cross the Cottonwood River. He named the town, Florence, in honor of his daughter.
