"Of whatsoever number a fleet of ships of war is composed, it is usually divided into three squadrons; and these, if numerous, are again separated into divisions"

William Falconer's quote provides insight into the normal organizational structure of marine fleets during his time. In essence, Falconer describes a hierarchical department approach that was commonplace in marine warfare technique. This system was crucial for effective command and control during complex maritime operations.

The initial part of the quote--"Of whatsoever number a fleet of ships of war is composed"-- suggests the versatility and scalability of the structure he is about to explain. No matter how big or small the fleet, this division technique aims to enhance its operation.

Falconer describes that a fleet is typically "divided into three squadrons". This tripartite division is tactical. With three squadrons, a fleet can cover more location, deal versatility in maneuvers, and maintain a balance between offensive and protective capabilities. Each squadron can be given a specific role-- such as searching, engaging the opponent, or securing the fleet's more vulnerable elements. Such a division improves command effectiveness, enabling admirals to collaborate actions while maintaining clear lines of interaction.

The 2nd part--"and these, if various, are again separated into departments"-- shows more granularity in the fleet's organization. When squadrons are "numerous", suggesting they consist of a large number of ships, dividing them into extra departments becomes required. This additional subdivision helps keep order and simplifies the complexities that come with commanding a large number of vessels. It makes it possible for more specialized assignments and targeted actions, enabling agile actions to altering conditions during naval engagements.

In conclusion, Falconer's description reflects a pragmatic and systematic approach to handling naval forces. This structure not only notifies how contemporary navies may be arranged but also offers historic context for comprehending marine technique. Through such an organized method, naval commanders of Falconer's era might successfully wield large and intricate fleets, guaranteeing maximized performance and tactical advantage at sea.
