Cape Ecnomus concentrates an immense fleet battle into one day

If a camera drone could record one historical naval battle, which would be most valuable to watch?

Cape Ecnomus, because it may be the largest naval battle ever concentrated into a single day and would clarify an exceptionally difficult ancient action.

The Battle of Cape Ecnomus is the chosen naval action for a camera drone to record. It is a strong candidate for the largest naval battle of all time, with roughly 290,000 people involved in a single day. That concentration differs from the much larger figures sometimes given for Lake Poyang, whose fighting extended from late August into early October and may mix naval and land forces. Duration and the categories being counted matter when ranking the scale of historical battles.
