 In the army of the Union
 We are marching in the van
 And will do the work before us
 If the bravest soldiers can;
 We will drive the Rebel forces
 From their strongholds to the sea
 And will live and die together
 In the Army of the Free
 The Army of the Free
 The Army of the Free
 We will live and die together
 In the Army of the Free
 We may rust beneath inaction
 We may sink beneath disease
 The summer sun may scorch us
 Or the winter's blast may freeze
 But whatever may befall us
 We will let the Rebels see
 The unconquered we shall remain
 The Army of the Free
 The Army of the Free
 The Army of the Free
 We will live and die together
 In the Army of the Free
 Though we live in winter quarters now
 We're waiting but the hour
 When Porter's brave division
 Shall go forth in all its power
 And when on the field of battle
 Fighting we shall be
 We'll show that we cannot disgrace
 The Army of the Free
 The Army of the Free
 The Army of the Free
 We will live and die together
 In the Army of the Free
 Then hurrah for our division
 May it soon be called to go
 To add its strength to those who have
 Advanced to meet the foe;
 God bless it, for we know right well
 Wherever it may be
 'Twill never fail to honor our great
 Army of the Free
 The Army of the Free
 The Army of the Free
 We will live and die together
 In the Army of the Free
