Recent large photometric, astrometric, and spectroscopic surveys have begun to uncover and characterise stellar streams and other faint, extra-tidal debris around the Milky Way. In parallel, cosmological simulations have reached sufficient resolution to enable studies of disrupting galaxies around Milky Way-mass hosts. In this talk, I will present predictions from cosmological simulations, semi-analytic modelling, and mock observations of the tangled web of galaxies unravelling about the Milky Way and its fainter satellites. Upcoming surveys detecting these faint tidal features (or not) will unlock new tests of hierarchical galaxy formation at the smallest scales.
