If Nelson had survived Trafalgar

What might Nelson's survival have meant for his and Collingwood's careers?

Collingwood probably still commands in the Mediterranean, while Nelson may return to the Channel Fleet or alternate major sea commands with him, but Nelson is unlikely to become First Sea Lord.

Collingwood probably still commands in the Mediterranean while Nelson might return to the Channel Fleet. Alternating distant commands could reduce the burden that historically kept Collingwood deployed for so long. Nelson's fighting reputation would still earn him fleet commands despite the political complications of his private life. He is unlikely to become First Sea Lord because administration and political management were not his strongest qualities.
