Which of the following were issues facing the north as the war dragged on? (there are more than one answer) -the blockade of union port cities, preventing trade -the staggering debt of a protracted war -shortage of military supplies and weapons -many women having to work outside the home -shortage of manpower due to many casualties

The North had its share of problems during the U.S Civil War. Late in the war, when victories are few and casualties are high, the Union employed conscription to alleviate manpower shortages.
