Frémont assassinated

Let's say Frémont wins the 1856 election but is killed in a Baltimore Plot type of situation. His Vice-President William Dayton becomes president. What kind of president would Dayton have been while the nation has a civil war? (Southern states secede and start a civil war just like they did OTL four years later.) Thanks.

It's kinda hard to know; it seems his strengths were on foreign policy/diplomacy but this is really based off his time as ambassador to France after his failed VP run. Before that experience he seems like a relatively obscure figure.
