“The President of the United States takes pride in presenting

		Navy Cross citation
Martin J. O'Brien was born on January 2, 1918 in Worcester, 
		Massachusetts. He attended Holy Cross where he was a second baseman for 
		the Crusader baseball team under former major leaguer Jack Barry. He 
		earned the starting spot as a sophomore, when the team posted a 10-6 
		record. During his junior year, the Crusaders lost their opening game 
		and then won their remaining 15, being declared Eastern Champions. 
		O'Brien batted .352 as a junior, and then .342 as a senior when he 
		scored 19 runs in 18 games. The Crusaders posted a 14-3-1 mark that 
		year. O'Brien also played three years of football at Holy Cross, with 
		his biggest game coming when he threw two touchdown passes against 
		Temple.
		
		O’Brien graduated in 1941 and went to work for the Norton Company of 
		Worcester. In February 1943, he left his wife Dorothea “Doris” (nee 
		McNamara) and entered the Marines. He trained at Parris Island, South 
		Carolina, and was commissioned at Quantico, Virginia.
		
		Second Lieutenant O’Brien was the leader of a Rifle Platoon attached to 
		the Second Battalion, Third Marines, Third Marine Division which landed 
		at Guam in July 1944. Ordered to attack Japanese positions at the crest 
		of Chonito Ridge on July 22, O'Brien led his platoon in a frontal 
		assault that was halted halfway by ferocious hostile machine-gun fire. 
		O’Brien withdrew his men to safety, reassembled and led a second attack. 
		Despite machine-gun, rifle, grenade and mortar fire, Martin O’Brien 
		reached the crest of the ridge before he was mortally wounded.
		
		For this act of extraordinary heroism, Second Lieutenant O’Brien was 
		posthumously awarded the Navy Cross. The citation reads as follows:
		
		“The President of the United States takes pride in presenting the Navy 
		Cross (Posthumously) to Martin J. O'Brien (0-25174), Second Lieutenant, 
		U.S. Marine Corps (Reserve), for extraordinary heroism as Leader of a 
		Rifle Platoon attached to the Second Battalion, Third Marines, THIRD 
		Marine Division, in action against enemy Japanese forces on the 
		Asan-Adelup Beachhead, Guam, Marianas Islands, 22 July 1944. Ordered to 
		attack enemy positions at the crest of a steep, bare ridge in an effort 
		to seize the high ground commanding the beachhead, Second Lieutenant 
		O'Brien courageously led his platoon in a determined assault until the 
		advance was halted halfway up the slope by withering hostile machine-gun 
		fire. Skillfully withdrawing the remainder of the platoon to a place of 
		cover, he promptly reorganized his units and, constantly exhorting his 
		men to follow him, again led the charge up the slope in the face of 
		terrific machine-gun, rifle, grenade and mortar fire, successfully 
		reaching the crest of the ridge before he was mortally wounded. By his 
		inspiring leadership and dauntless fighting spirit under extremely 
		perilous conditions, Second Lieutenant O'Brien enabled his platoon to 
		gain its objective, and his self-sacrificing devotion to duty throughout 
		reflects the highest credit upon himself and the United States Naval 
		Service. He gallantly gave his life for his country.”
		
		O’Brien Square in Worcester, Massachusetts, was dedicated to 2/Lt. 
		Martin O’Brien. It is located at
		Lake Park on the Hamilton Street side, near Field House.
		
		O’Brien was inducted in the Holy Cross Sports Hall of Fame in 1998. His 
		widow, Doris, never remarried. She passed away in Worcester in December 
		2009, aged 91.
