The locations of Brest and Toulon turn geography into a fleet-logistics problem. Moving ships between the two coasts meant sailing around Spain and past Gibraltar, so France needed separate support systems, yards, and force structures rather than one easily concentrated home fleet. The same passage connects that division to practical weaknesses in scouting, destroyer leadership, and submarine machinery, showing why nominal ship totals overstated usable strength. A later comparison with the U.S. Navy explains the value of the Panama Canal: a two-ocean fleet with a shortcut could reinforce across coasts far more readily than France could.

Two coasts forced France to duplicate fleet support
Brest, Toulon, Spain, and Gibraltar explain why France could not combine its Atlantic and Mediterranean forces as readily as an island navy could.
