Calder served as captain of the fleet to John Jervis at Cape St Vincent, a trusted position at the center of fleet control aboard Victory. Nelson's famous intervention in the same battle supplies the more aggressive model of independent initiative. Jervis could have made Calder a commodore or assigned him wider authority, yet kept him in the central staff role. That choice suggests Jervis valued Calder's seamanship and reliability without seeing him as an officer to release on independent operations.
