After ''British Chivalry'' sank, ''I-37'' turned her attention to the lifeboats, opening fire on them with her [[Type 96 25 mm AT/AA Gun|25-millimeter]] [[antiaircraft gun]]s.<ref name=edwardsp92>Edwards, p. 92.</ref> When an officer aboard one of the boats signaled ''I-37'' for instructions by [[semaphore]], ''I-37'' ceased fire<ref name=edwardsp92/> and ordered the boats to come alongside one at a time.<ref name=combinedfleetI37/><ref>Edwards, pp. 92–93.</ref> ''I-37''′s medical officer interrogated the men in the lifeboats,<ref name=combinedfleetI37/> and ''I-37'' brought Captain Hill aboard as a prisoner-of-war,<ref name=combinedfleetI37/><ref name=edwardsp93>Edwards, p. 93.</ref> forcing him to surrender his [[briefcase]], which contained about fifty [[diamond]]s and [[sapphire]]s.<ref name=combinedfleetI37/> ''I-37'' ordered the motorized lifeboat to take the other boat in [[Towing|tow]] and head westward, and ''I-37'' proceeded toward the east.<ref name-=edwardsp94>Edwards, p. 94.</ref> ''I-37'' then reversed course and approached the boats at speed,<ref name-=edwardsp94/> and Nakagawa ordered the crew of ''I-37''′s floatplane and two members of ''I-37''′s crew to open fire on the survivors,<ref name=combinedfleetI37/> with Captain Hill forced to stand on deck and watch.<ref name=edwardsp104>Edwards, p. 104.</ref> For 90 minutes, ''I-37'' repeatedly passed within a few yards of the boats and fired on them, holing them and killing and wounding men who had gone overboard and clung to the sides of the boats for cover, as well as fishtailing her [[stern]] back and forth through the water around the boats to slice up men in the water with her propellers.<ref>Edwards, pp. 94–95.</ref> At 14:00, {{frac|3|1|2}} hours after torpedoing ''British Chivalry'', ''I-37'' finally ceased fire and headed off to the east after killing 13 men and wounding five on the boats and in the water.<ref name=combinedfleetI37/><ref>Edwards, p. 95.</ref> After drifting {{convert|320|nmi}} to the south-southwest over the next 37 days, ''British Chivalry''′s 38 survivors — 29 crewmen and nine gunners — finally were rescued by the British merchant ship {{SS|Delane}} at {{coord|04|55|S|065|32|E}}.<ref name=combinedfleetI37/><ref>Edwards, p. 103.</ref>
 
While ''I-37'' was on the surface in the [[Arabian Sea]] {{convert|200|nmi}} west of [[Diego Garcia]] at 20:30 on 26 February 1944, her lookouts sighted the British 5,189-gross register ton armed [[motor vessel]] {{MV|Sutlej}}, which had detached from a convoy to proceed independently during a voyage from [[El Qoseir|Kosseir]], [[Egypt]], to Fremantle, Australia, with a cargo of 9,700 tons of [[Phosphorite|rock phosphates]] and [[mail]].<ref name=combinedfleetI37/> Soon after dark, the submerged ''I-37'' fired two torpedoes at ''Sutlej'' from a range of {{convert|2,190|yd|m|sigfig=3}}.<ref name=combinedfleetI37/> One torpedo hit ''Sutlej'' in her port side, and she sank four minutes later at {{coord|08|S|070|E|name=MV ''Sutlej''}}.<ref name=combinedfleetI37/> Her survivors abandoned ship in a lifeboat and several life rafts.<ref name=combinedfleetI37/> ''I-37'' surfaced and used a [[searchlight]] to illuminate the area, discovering a teenage [[Indian people|Indian]] boy clinging to her [[rudder]].<ref name=combinedfleetI37/> After ''I-37'' took him aboard, her medical officer interrogated the other survivors in an attempt to identify ''Sutlej''′s master, who apparently had died in the torpedo explosion, and to gather information about ''Sutlej''′s cargo and destination.<ref name=combinedfleetI37/> Nakagawa then ordered ''I-37''′s crew to open fire on the survivors.<ref name=combinedfleetI37/> In the sinking and subsequent gunfire, 41 crew members and nine gunners from ''Sutlej'' perished.<ref name=combinedfleetI37/> The [[Royal Navy]] [[whaler]] {{HMS|Solvra}} rescued ten crewmen and a gunner after they spent 42 days on a life raft,<ref name=combinedfleetI37/> and the [[Royal Navy]] [[sloop-of-war]] {{HMS|Flamingo|L18|6}} rescued 11 crewmen and a gunner after they had drifted at sea for 46 days.<ref name=combinedfleetI37/>
