Q&A: Could Russia have outlasted Japan on land?

Could Russia eventually have won the land war because reinforcements were arriving while Japan struggled to replace its losses?

Not automatically; Russia's reinforcements were less well trained, and its weak logistics prevented the army's growing paper strength from being used effectively.

Russian reinforcement totals did not make victory inevitable. Troops arriving over the Trans-Siberian Railway were generally less well trained than the Japanese troops they faced. Russia also lacked the supply network needed to move and sustain its paper strength far enough from the railway to use it effectively. Japan was reaching the end of its own logistics line, which helps explain the inconclusive late fighting, but mutual exhaustion did not turn Russian manpower into deployable combat power. Available soldiers mattered only when the army could train, transport, feed, and command them.
