The ocean connects the Grand Isles, Silvia and distant Allied efforts. Kelonese participation against Hestunia in 1209 places shipping under threat long before Silvia becomes a combatant. Convoys, repair, minesweeping and reconnaissance matter because even powerful armies cannot fight without delivered cargo.
Strategy & the wider war
A convoy battle can be a strategic success despite ship losses if essential cargo arrives. Conversely, a fleet can win an exchange and fail its transport mission. The proposed maritime battles therefore track passage, unloading and repair rather than inventing unsupported kill totals. The source archive’s fleet actions provide the visual and chronological foundation.
