An expedition can land at a Mexican port instead of marching across the region from an existing frontier. The harbour provides a short approach to Mexico City and makes the capital a practical operational objective. Capturing the city could remove a large share of Spain's local army-production capacity in the campaign. Naval transport and a coastal entry point thus turn an inland political and industrial centre into a reachable target.
