The Thirteenth New Hampshire Regiment endured another week of exceedingly hot weather in camp. The intense heat and the poor quality of drinking water resulted in a breakout of diphtheria. Today the Thirteenth was engaged in the usual fashion in inspection and dress parade, and also received the news that the Seventh Corps was being dissolved and that they were transferred to the Eighteenth Corps.1
