In March 2558, Jespersen was present onboard Infinity during Fleet Admiral Terrence Hood's diplomatic mission to Ealen IV. During the peace talks, Infinity lost radio contact from the surface. Jespersen alerted Commander Bradley that communications were lost and that the Jiralhanae demanded to know why Infinity was supposedly blocking their communications. Unknown to them all, the delegation had come under attack by Covenant mercenaries.
As Chieftain Lydus' fleet began bearing down on the Arbiter's fleet in response to the communications block. Jespersen received a transmission from Captain Lasky and patched him through to Bradley. Captain Lasky ordered all fleets to stand down and direct their ships to the planet in order to save their diplomats. The fleets rallied with Infinity and forced the Covenant mercenaries into retreat.
