Why did Louis-Philippe leave France in 1793?

Louis-Philippe left France in 1793 primarily because he deserted the Revolutionary cause following the French defeat at the Battle of Neerwinden in March 1793.1

After serving as a Jacobin officer and fighting in the French Revolutionary wars, Louis-Philippe associated himself with his commander, Charles-François du Périer Dumouriez, in abandoning the Revolutionary government and coming to terms with the Austrians. Rather than joining the enemies of France, he chose to go into exile in Switzerland, where he reunited with his sister, Adélaïde. His departure and subsequent desertion led to the arrest of his father, Philippe Égalité, in Paris.1
