Mosby's Raiders puts you in command of the Partisan Rangers. Your mission is to infiltrate enemy lines to disrupt the Union war effort. As you succeed in your operations, your notoriety grows and the Union devotes additional troops to stopping you. You select the Union targets for your raids and decide which actions Mosby's Raiders will perform. You may be deep inside Union lines when the Union Army is alerted by your activities and begins to pursue your band. As more Union troops join in the chase, you must either try to escape or stop to take on the Union units in combat. Events beyond your control may lead to Union sweeps that diminish your Confederate support or you may find yourself gaining unexpected reinforcements.
