The President of the United States of America takes pleasure in presenting the Navy Cross to Second Lieutenant Samuel Sloan Jack (MCSN: 0-4252), United States Marine Corps, for distinguished service in the line of his profession as aviator while attached to the Second Marine Brigade operating in the Republic of Nicaragua. On 12 April 1931, Lieutenant Jack in the face of machine gun and rifle fire from bandits, located and most effectively bombed a bandit camp near Moss Farm, Nicaragua. On 13 April 1931, he assisted in effecting a crossing of the Snaki Bridge by ground patrol and thereafter located a bandit camp at Logtown; this information he delivered to the ground patrol which he guided to the scene, meanwhile, at great personal risk, effectively harassing the enemy and pinning him to the ground with machine gun fire until arrival of the patrol. The ensuing engagement resulted in the death of the notorious Sandino jefe, Pedro Blandon, on of the most brilliant successes in the Nicaraguan campaign.
