What if the Russian Second Pacific Squadron evaded interception and reached Vladivostok during the Russo-Japanese War?
Short answerIt could rearm temporarily, but Vladivostok could not support the force and Japan would blockade and bombard the port, probably prolonging rather than changing Russia's defeat.
NotesReaching Vladivostok would prolong the campaign without rescuing the Russian fleet. The squadron could rearm and reorganize temporarily, but the port was not equipped to supply, repair, and work up a force of that size. Japan could concentrate on blockading and bombarding Vladivostok instead of fighting the historical battle at Tsushima. More Russian sailors might survive the first interception, yet continued operations from an inadequate base could ultimately increase losses. Basing and sustainment determine whether a tactical escape has any strategic value.
