The first 48 hours of the Second Dainamese–Mosesian War saw the conflict expand rapidly along the entire frontier. As the nationwide mobilization continued, the People’s Army established several major forward sectors along the border. Dainamese formations advanced behind the initial air campaign, while reserve units began arriving to reinforce the most heavily contested areas. The General Staff declared that the first objective was to secure the frontier and prevent Mosesian forces from concentrating against any single sector. The heaviest fighting developed in the northern sector, where several Dainamese formations pushed into positions previously occupied by Mosesian border units. Dainamese forces captured several abandoned military positions and logistical sites as Mosesian units withdrew toward more defensible ground. However, the advance slowed as Mosesia began establishing a continuous defensive line around the region's major transportation corridors. Dainamese units launched simultaneous advances from several directions, forcing Mosesian commanders to redistribute their forces. Several local counterattacks were reported, but none succeeded in restoring the original front line. By the end of the second day, the central front had become the main concentration of both armies.
