p. 478	Col. Michael H. Spangler and His Company of York Troops at the Battle of North Point, Baltimore. From Glossbrenner's History.  "In 1814, when the city of Baltimore was endangered by the approach of the British, York county was prompt in coming forward to the aid of the Baltimoreans.  A number of companies in various parts of the county were immediately ready to march to the city, prepared to confront the proud invader, and, if necessary, to lay down their lives in the effort to check his progress.  "Although, of the companies raised here for the purpose of defending Baltimore, but one reached the city in time to share the danger and glory of an actual engagement with the enemy--yet, the fact that they marched to the point of invasion as early as circumstances permitted, will shield all of them who did not arrive in time, from any imputation of indifference to the fate of Baltimore.  When they did leave their homes, they left them in the full expectation that they were to meet an enemy flushed and insolent with success, and surpassing them in military discipline. It was no fault of theirs that, when they arrived at Baltimore, an attack had already been made--it was no fault of theirs that they had not assisted in the gallant defense of the city and the repulse of the invader.  "The 'York Volunteers,' who did arrive in time, were nearly one hundred strong, were composed principally of young men, 'the flower of the county,' and were commanded by Captain (afterwards Colonel) Michael H. Spangler, of the borough of York.  "This gallant company marched from York on the 29th of August, 1814, without any provisions other than that contributed by the citizens of the borough. Immediately upon their arrival at the city, they tendered their services to the general in command, and in consequence of their respectable appearance and discipline, were solicited to attach themselves to the fifth regiment, a fine body of Baltimore troops, under the command of Col. Sterett. They were marched with their regiment to oppose the enemy at North Point, and until overpowered by numbers, fought with the bravery of veterans.  "Notwithstanding the formidable host opposed to them, they resolutely maintained their ground, until a retreat, thrice ordered, became absolutely necessary to prevent their being surrounded and cut off. Two of their number were taken prisoners and several wounded--one very severely. After the battle, and until the enemy retired, their duty was of the most severe and arduous kind, and they acquitted themselves in a manner fully satisfactory to their commanders, and highly honorable to themselves.
p. 479	"In testimony of the gallant bearing of the 'Volunteers' at Baltimore, we subjoin the discharge of Gen. Smith, a private letter of Maj. Heath, and an extract from the regimental orders of the brave Col. Sterett, of September 20, 1814."  HEADQUARTERS, Baltimore, September 20, 1814. "Captain Spangler and his company of volunteers from York, Pa., having honorably performed the tour of duty for which they had offered their services, are hereby permitted to return to their homes. In taking leave of this gallant corps, the Major General commanding has great pleasure in bearing testimony of the undaunted courage they displayed in the affair of the 12th inst., and in tendering them his thanks for the essential aid they contributed towards the defense of this city.  "S. SMITH, Maj. Gen. Commanding." "BALTIMORE, September 20, 1814.  "TO CAPTAIN SPANGLER,  Dear Sir:--Hearing that you are about to depart from our city with your brave corps, I cannot do justice to my own feelings without expressing the obligations I am under to you and them for the promptness with which you uniformly executed my orders, your readiness at all times to perform your duty, and the cool and manly conduct manifested by the officers and men under your command during the action with the enemy on the 12th inst. May you all return in health to the bosoms of your families, and long enjoy happiness uninterrupted.  "I am sir, with sentiments of sincere respect, your friend and humble servant,  "R. K. HEATH, 1st major, 5th reg't." REGIMENTAL ORDERS--FIFTH REGIMENT.  "BALTIMORE, Sept. 20, 1814. "Captain Spangler's company of York Volunteers having permission to return to their respective homes, the Lieutenant Colonel cannot permit them to depart without thanking them for their soldier-like and orderly conduct.  The few days they were attached to the 5th regiment was a momentous period of trial--they not only had to face the dangers of battle but to bear the inclemencies of weather and suffer all the inconveniencies of fatigue, watching, and hunger, to which a soldier is liable in the hour of alarm--these were met and borne by them with a manly fortitude, which does them honor and entitles them to the gratitude of Baltimore and particularly to the friendship and esteem of the officers and men of the 5th regiment, which are thus publicly and cheerfully accorded to them. "The following is a list of the officers and men composing the company of 'York Volunteers,' when that company marched from York on the Invasion of Baltimore August 29, 1814..."
