On May 3, McClernand wrote to USG. "You doubtless received this morning, the copy of a communication from Genl Halleck, instructing me to advance with my command—One of my orderlies bearing an order to Genl Van Cleve, in command of Crittenden's Division, to move accordingly, in the morning, has just returned informing me that Genl. Van Cleve is moving forward to Monterey, to-day. The presumption is, that Genl Van Cleve's movement is being made pursuant to an order from some other source—Besides this disarrangement, I am also in posession of a note from Genl Buell requesting me to send Sutermeister's heavy battery in compliance with a telegram from Dept Head Quarters—This request seemingly conflicts with the order of Genl Halleck to me, of this date, yet, in view of explanations made by one of Genl Buell's officers, I sent the battery forward—Such conflicting orders, and authority must necessarily lead to confusion, and make it [impracticable] for me to answer the expectations either of Genl Halleck or yourself—... P. S. At this moment Genl Buell sends an extract of Genl Hallecks order rescinding the order attaching Gen Crittendens Division to my army Corps—Will its place be supplied ?"
