Charles, nearly 1,200 men. It is the last new regiment raised in the State. The War Department authorized Gen. Farnsworth to get it np. A majority of the men were recruited In Northern Illinois, but several companies are from Egypt-. The field officers are all experienced men who have been in actual service and seen war in all Its shapes, from the hungry bivouac in the mud to the fiery straggling battle. The regiment completed its organization last Friday under the auspices of Adjutant Gen. Fuller, and was mustered into the service of the U. S. by .Capt. Pomeroy, Mustering and Disbursing officer in this city.The regiment will be filled immediately, and it Is expected will take the field early in. the next campaign.The following is the Boater of the Field and Staff: • • 'Colonel—John L. Beveridge.Lieut. Colondr-D. J. Hynes.?stMajor—Hiram Hilliard..2d Major—L. A. Matlock.3d Major—P. E. Fisher. •Surgeon—J. K. Crawford,let Assistant Surgeon—Bobert T. Sill.2d Assistant Surgeon—A. J. Willing.Adjutant—Samuel W. Smith.Quartermaster—Philo P. JndsonuCommissary—John Cotton.Col. Beveridge's original entry - into the service was as Major of the tin I1L cavalry on the 18th September, 1861. During their last eompaign, axtd the cumin which - the cavalry of the army of the Potomac most distinguished itself, he was in command, and the gallant bearing of the regiment in the most trying places Is largely attributable to his bravery, discretion and fitness for command. We know of no more deserving or gallant soldier to whom the new regiment could be entrusted.Lieut. CoL Hynes enlisted into the 8th III. cavalry as a private in Capt. Medlii’s company, in Sept., 1861, was elected Second lieutenant on the organization of the company, was promoted to the Captaincy when Capt. HeoQl was made Major, which rank he held until he was appo’utcd Lieut. Colonel of the 17th cavalry. H6 performed considerable duty while in the Potomac army, as aid to Gen. Sumner, and after his death, to Gen. Pleasanton. He was a favorite with both for his promptness, fearlessness, activity and gallant nearing ana efficiency as an aid, being equally ready with the sword or pen. In achanje hewas always in the front, and in a retreat the filndmsst. He never hesitated to expose himself in darurer, and ever set an example to his men of courage and dash. He was boro to be a cavalry officer. We feel a pride in the handsome distinction he has won, and in the highly.complimentary letters that followed him home, written by his superior officers, as be is one of thcTnia-uxn boys, having learned hla trade in this office, end enlisted out of It as one of tbe forty-seven men cent from this establishment to fight for the Union and Liberty.Major Hilliard was formerly an officer in the 1st Wisconsin Cavalry, and served with it in Us glorious campaigns in Arkansas and Missouri, and always with distinction and credit to himself and his profession. .. . .Major Matlock will be remembered as the Chaplain of the 8th Illinois Cavalry, and while in that regiment, was always as popular for his readiness to take part in an engagement, as to deliver, an admirable eermon. He was as skilled in the use of carnal weapons, as he was in spiritual.Major Fisher was formerly a captain In the 2th Illinois Cavalry, and has distinguished himself on many a hard-fought field. He went into the war for the Union in tbe 1st Wisconsin Infantry, and carried the colors triumphantly In the spirited engagement of that regiment with the enemy at Falling Waters, early fn '861. He was .wounded at Gettysburg, but is now recovered, and able to assume bis new honors. ysiTbe Surgeon, Dr. Crawford, of St. Charles, is considered a most skillful as well as humane physician, and the experience which he has acquired, as Aesistant-Surgeon of the 8th Illinois cavalry, will render him invaluable in his new position.Assistant Surgeon Sill is a graduate of Bush Medical College of this city. His original entry into the service was as Hospital Steward of the 8th Illinois cavalry. In which capacity he served during the active campaigns in Virginia, and has thus acquired an experience which well befits him for bis position. Hi health compelled him to resign the AdJutantcy of the Eighth, to which be was appointed, ana in which he served daring the latter part of his connection with that regiment.Second Assistant Surgeon has also acquired ex-Sericnce as Steward in the 8th Illinois,and is veiy eecrving of his promotion.Adjutant Smith was formerly Sergeant Major of the fcth Illinois -cavalry, and during the varied changes in that office, continued to discharge the entire duties in a manner which reflected upon him the highest credit.Quartermaster Judson was formerly Commissary Sergeant of the £th Illinois cavalry, and by the manner in which he has performed the duties of his new position, his genial manners, and the readiness with which it Is his pleasure to supply the wonts of the regiment, has won for-himself hosts of friends. We learn he has been recently appointed a Captain in the Commissary Department; and while we congratulate him upon his promotion, we regret his loss.CommifEary Cotton Is a nephew of Gen. Farnsworth, and is esteemed an efficient man.The line officers of the regiment are all more or less experienced, and were complimented very highly by General Fuller, as were also their respective commands upon their splendid appearance. The General himself Is universally popular with the Blinols military, and was cheered repeatedly while on the grounds.The Birth Day of Robert Burns.
