==February==
*10: Commander T'Pol of the Enterprise officially takes an "extended leave of absence" and returns to Vulcan at the request of Captain Jonathan Archer in order to contact Administrator T'Pau and attempt to ascertain the reason for the Vulcan's reticence to fully enter the Earth-Romulan War.
==March==
*8: The Enterprise returns to Earth after a nearly eight month journey from Gamma Hydra.
*10: The Rihannsu ship Dhivael attacks Andoria, but is destroyed when the NX-class starship Challenger activates its self-destruct system and rams the Rihannsu vessel.
**T'Pol discovers T'Pau in isolation at Vulcan's Forge, where she is serving as a living vessel of the katra of Surak.
*15: Preator D'edridex dies in a skimmer "accident", assassinated by elements of his own military and the Tal'Shiar after his decision to launch a second war against Haakona, leading to the loss of several vessels in a single battle. Karzan succeeds him.
*18: The Haakonans counter-attack the Rihannsu at the Uaenn Ei'krih Outpost, using weaponry supplied secretly by the Vulcans and drawing the Rihannsu further into the late-Preator's second war.
==April==
*2: An Earth Starfleet task force led by the Enterprise launches a counter-attack at Berengaria VII. Though it results in the loss of seven Deadalus-class ships, the battle is a success. However, the use of helmets and vaporization of their own dead by Rihannsu forces means that Human ground troops never see their enemies' faces.
*4: The Columbia begins an escort mission to the Onias Sector. They are ambushed by Rihannsu ships, who use their tele-capture system to take control of the Columbia and use its weapons to destroy the convoy. The crew manages to escape, but are unable to communicate their survival. They are declared missing until the vessel itself is found in the Gamma Quadrant in 2373.
==May==
==June==
*20: The Rihannsu launch a second attack on Altair VI, but are stopped by the Endeavor.
**T'Pol returns to the Enterprise, having failed to convince the Vulcans to take a more active role in the war.
**A combined Human, Andorian, and Tellarite fleet led by the Enterprise retakes Deneva.
**The Rihannsu take Tau Ceti IV. Among the vessels lost is the Atlantis.
*21: Due to their losses and susceptibility to the Rihannsu tele-capture system, both the Andorians and the Tellarites withdraw their fleets from the front-lines to concentrate on the direct defense of their home systems.
**On Vulcan, a Rihannsu infiltrator sets of a bomb at Vulcan's Forge, destroying the katra of Surak.
*22: The Enterprise travels to Qo'nos to attempt to convince the Klingon Empire to enter the war.
