What did john brown hope to accomplish with his raid on the arsenal at harpers ferry, virginia?

united states reinforcements contributed greatly to three allied victories in france at: cantigny (first major american battle), argonne (the largest in the united states military history, involving 1.2 million american soldiers), and château-thierry (one of the first actions under general pershing).

the first two years of american revolution was not very encouraging for the patriots since the british were far superior in sea power, arms and troops.
