"For extraordinary heroism and devotion to duty while serving with the Fifth Regiment United States Marines. Under heavy shell fire, on April 23, 1918, he rushed to the assistance of Corpl. Thomas Regan, who was seriously wounded, and administered such effective surgical aid while bombardment was still continuing, as to save the life of Corporal Regan. (Act of February 4, 1919.)
Seaman, serving on board the U.S.S. _Pensacola_; in the attack on Forts Jackson and St. Philip, April 24, 1862, was lashed outside of that vessel, on the port-sheet chain, with lead in hand, to lead the ship past the forts, and never flinched, although under a heavy fire from the forts and rebel gunboats. (G.O. 169, February 8, 1872.)
Boy, U.S.S. _Brooklyn_; in the engagement in Mobile Bay, August 5, 1864; conspicuous for bravery, performing his duty in the powder division, at a point where the ship was riddled very much, and in the immediate vicinity of the shell whips, which were twice cleared of men by bursting shells. (G.O. 45, December 31, 1864.)
Captain of top on board of the U.S.S. _Brooklyn_; in the engagement in Mobile Bay, August 5, 1864; activity, zeal, and skill displayed in handling his gun, as well as great courage. He was severely wounded. (G.O. 45, December 31, 1864.)
Seaman on board the U.S.S. _Hendrick Hudson_; was one of the men of a howitzer's crew cooperating with the Army in the military and naval expedition to St. Marks, Fla., March 5 and 6, 1865, and was commended for coolness and determination under fire, remarkable efforts in assisting to transport gun, and for remaining by gun throughout a severe engagement in a manner highly creditable to himself and to the service. (G.O. 59, June 22, 1865.)
Chief boatswain's mate, United States Naval Reserve Force, on board the U.S.S. _Remlik_. On the morning of December 17, 1917, the _Remlik_ encountered a heavy gale. During this gale there was a heavy sea running. The depth-charge box on the taff rail aft, containing a Sperry depth charge, was washed overboard, the depth charge itself falling inboard and remaining on deck. Mackenzie, on his own initiative, went aft and sat down on the depth charge, as it was impracticable to carry it to safety until the ship was headed up into the sea. In acting as he did Mackenzie exposed his life and prevented a serious accident to the ship and probable loss of the ship and entire crew. (G.O. 391, May 8, 1918.)
