The President of the United States takes pleasure in presenting the Navy Cross to Donald McGregor, Lieutenant Commander, U.S. Navy, for extraordinary heroism and distinguished service in the line of his profession as Commanding Officer of the U.S.S. GAR (SS-206), during the FIRST War Patrol of that vessel in enemy controlled waters during the period 2 February 1942 to 28 March 1942. Despite strong enemy countermeasures and unfavorable sea conditions, Lieutenant Commander McGregor took advantage of every opportunity to strike the enemy and in a series of skillfully conducted attacks succeeded in sinking 10,500 tons of enemy Japanese shipping without casualty to personnel of his own command. Lieutenant Commander McGregor's conduct throughout was an inspiration to his officers and men, and are in keeping with the highest traditions of the Naval Service.

Initially commanded by CDR Don McGregor; Seahorse took a shakedown cruise, and reached the Pacific in summer 1943.

Seahorse's first war patrol began on 3 August 1943. "It was not successful. Stationed off the Palaus, McGregor made only two attacks and allowed a number of convoys pass by unscathed. After the boat returned to port, an investigation of her poor performance" by Vice Admiral Charles A. Lockwood, [Commander, Submarines, Pacific Fleet: COMSUBPAC] and his staff led to McGregor's removal for not being aggressive enough." Cutter was named Commanding Officer of Seahorse in October 1943.
