Battle Stragities that were used in Act 4 and 5 of "Julius Caesar"

My project that I did for English was about the map's and battle stragities of act's 4 and 5. There were 2 battles. In those two battles Cassius and Brutus both killed themselves by running on their own swords that they killed Julius Caesar with. Both the battles were in Philippi, which is located near Greece.
