71. In all fencing while maintaining the pressure in the engage, a certain freedom of motion of the rifle is allowable, consisting of the play, or up-and-down motion, of one bayonet against the other. This is necessary to prevent the opponent from divining the intended attack. It also prevents his using the point of contact as a pivot for his assaults. In changing from one engage to the other the movement is controlled by the left hand, the right remaining stationary. 72. After some exercise in _engage_, _engage left_, and _counter_, exercises will be given in the _assaults_. ASSAULTS. 73. The part of the body to be attacked will be designated by name, as head, heck, chest, stomach, legs. No attacks will be made below the knees. The commands are given and the movements for each line are first explained thoroughly by the instructor; the execution begins at the command _assault_. Number one executes the attack, and number two parries; conversely, at command, number two attacks and number one parries. 74. For convenience in instruction _assaults_ are divided into _simple attacks_, _counter attacks_, _attacks on the rifle_, and _feints_. SIMPLE ATTACKS. 75. Success in these attacks depends on quickness of movement. There are three simple attacks--the _straight_, the _disengagement_, and the _counter disengagement_. They are not preceded by a feint. 76. In the _straight_ the bayonet is directed straight at an opening from the engaged position. Contact with the opponent's rifle may, or may not, be abandoned while making it. If the opening be high or low, contact with the rifle will usually be abandoned on commencing the attack. If the opening be near his guard, the light pressure used in the engage may be continued in the attack. Example: Being at the _engage right_, 1. _Number one, at neck_ (head, chest, right leg, etc.), _thrust_; 2. _Number two, parry right_; 3. _ASSAULT_. 77. In the _disengagement_ contact with the opponent's rifle is abandoned and the point of the bayonet is circled _under_ or _over_ his bayonet or rifle and directed into the opening attacked. This attack is delivered by one continuous spiral movement of the bayonet from the moment contact is abandoned. Example: Being at the _engage right_, 1. _Number one_, at stomach (left chest, left leg, etc.), _thrust_; 2. _Number two, parry left_ (etc.); 3. _ASSAULT_. 78. In the _counter disengagement_ a swift attack is made into the opening disclosed while the opponent is attempting to change the engagement of his rifle. It is delivered by one continuous spiral movement of the bayonet into the opening. Example: Being at the _engage right_, 1. _Number two, engage left_; 2. _Number one_, at chest, _thrust_; 3. _Number two, parry left_; 4. _ASSAULT_. Number two initiates the movement, number one thrusts as soon as the opening is made, and number two then attempts to parry.
