The little blue ribbon has 13 stars.  Not an unlucky number, unless your name is King George.  It was created at the time of the Civil War.    The first one struck was for the Navy, then from the same die was struck the Army version. (The Navy medal has an anchor.)  The title is a link to a page where you can look over the various editions.

He was a platoon runner, when the unit assembled near Wesel, Germany after a descent east of the Rhine. Attacking along a railroad, Company E reached a point about 250 yards from a large building used as an enemy headquarters and manned by a powerful force of Germans with rifles, machineguns, and 4 field pieces.

One platoon made a frontal assault but was pinned down by intense fire from the house after advancing only 50 yards. So badly stricken that it could not return the raking fire, the platoon was at the mercy of German machine gunners when Pfc. Stryker voluntarily left a place of comparative safety, and, armed with a carbine, ran to the head of the unit. In full view of the enemy and under constant fire, he exhorted the men to get to their feet and follow him. 

Inspired by his fearlessness, they rushed after him in a desperate charge through an increased hail of bullets. Twenty-five  yards from the objective the heroic soldier was killed by the enemy fusillades. His gallant and wholly voluntary action in the face of
overwhelming firepower, however, so encouraged his comrades and diverted the enemy's attention that other elements of the company were able to surround the house, capturing more than 200 hostile soldiers and much equipment, besides freeing 3 members of an American bomber crew held prisoner there. 

The intrepidity and unhesitating self-sacrifice of Pfc. Stryker were in keeping with the highest traditions of the military service.
