Why sea time forged Nelson's captains into a team

Did French and Spanish captains have an equivalent to Nelson's band of brothers?

They had the potential, but too little shared sea time to build the same cohesion before Trafalgar.

French and Spanish captains had the potential to form a close professional team, but they spent less time together at sea. Shared operations forced officers to cooperate against the sea's dangers and the enemy. Rivalries had to give way when disputes could cost ships or an entire fleet. Port brought officers closer to political interference and local divisions, a problem that also affected the Royal Navy.
