The 18th Infantry Regiment, U.S. 1st Infantry Division, commanded by Col. George A. Smith Jr., directed its 1st Battalion (commanded by Lt. Col. Henry G. Leonard, Jr.) to take the hill employing special pillbox assault teams equipped with flamethrowers, Bangalore torpedoes, and demolition charges. A battery of tank destroyers and self-propelled guns were to provide supporting direct fire at the pillboxes. As the leading rifle platoon of C Company assaulted the first pillbox, flanking fire from a nearby pillbox gun emplacement took the platoon in crossfire. The pinned-down soldiers also experienced an intense artillery barrage on their exposed positions.
Capt. Bobbie E. Brown was the company commander of C Company, a former boxer who had earned a battlefield commission in Normandy. During the onslaught of the nearby pillbox, Capt. Brown grabbed a pole charge and ran 100 yd (91 m) with bullets whipping by him, and placed the charge in the pillbox, destroying it. He did this twice more to two other pillboxes, each time successfully destroying the pillbox; only on the third one was he wounded by a mortar round. Although he was wounded, he refused medical attention and continued up the hill. After the hill was secure, he went by himself on a reconnaissance mission to locate enemy troops beyond the hill. He deliberately drew the enemy fire to find out where enemy emplacements were. While doing this, he was wounded twice more. The information he discovered about German emplacements allowed his company to repel two German counterattacks. Only after the position was completely secure did he allow treatment for his wounds. For his actions during the Battle of Crucifix Hill, Capt. Brown received the Medal of Honor.
