Within a simulated Milky Way-like galaxy, we identify and analyse analoguesof the Gaia-Enceladus (GE), Kraken and Sequoia mergers that each matchesremarkably well observational results, including in velocity and chemicalabundance space, and their distributions in the $j_{z}$-Energy plane. TheKraken analogue is the earliest merger and has the highest total mass ratio.Consistent with previous studies, it is chemically indistinguishable from oldin-situ stars at the time of its accretion. The GE and Sequoia analogue eventsaccrete at similar times in our simulation, both along filaments but fromopposite sides of the main galaxy. The mean stellar ages of the GE and Sequoiaanalogues are both similar and, from our simulation results, we see that theycan be separate entities and still naturally reproduce the observed propertiesof their stellar remnants at the present day, including the significantretrograde velocities of the Sequoia analogue remnant stars and the differencein the tracks of the two galaxies through chemical abundance space. Our resultsprovide supporting information about the properties of these three mergerevents, and show for the first time that they can all be reproduced with afully cosmological simulation, providing a possible self consistentevolutionary pathway for the Milky Way's formation.
