I want to know the answer to the following question:
The French Marines and naval infantry were dispatched to reinforce what?
All the background I'm provided with is that "A shortage of officers, following the capture of most of the professional French army at the Siege of Metz and at the Battle of Sedan, led naval officers to be sent from their ships to command hastily assembled reservists of the Garde Mobile.". Is that enough to answer the question?
Answer: no
