1942

On 28 August 1942, he set off from Pearl Harbor on his first war patrol (the Grouper second) to patrol the East China Sea.

On 21 September, off the coast of Shanghai, McGregor made his first kill, sinking the Japanese transport Tone Maru.

Near Qing-bang, Dongji Islands, in the eastern Zhoushan Archipelago on 1 October Grouper fired on the Japanese transport Lisbon Maru which was, unknown to the Grouper, transporting about 1,800 prisoners of war.

Three of Grouper torpedoes missed, but the fourth one hit, "stopping the freighter dead in the water" Grouper fired two more torpedoes, one of which hit.

When an enemy aircraft appeared and dropped depth chargers on Grouper, it dived to escape.

The sinking resulted in deaths of more than 800 British prisoners.

Grouper arrived in Midway on 21 October, credited with 12,000 tons of enemy freight sunk, for which McGregor was awarded the Silver Star for "conspicuous gallantry and intrepidity in action".

Grouper was refitted at Midway and had an SJ radar installed.

On 12 November, Grouper embarked for the Solomon Sea.

McGregor waited until the last destroyers were passing, but an Allied air raid on the convoy caused his target to alter course, ruining his chance to attack.

Grouper continued its patrol, gathering intelligence on Japanese radar stations, and arrived in Brisbane on 18 March.
