Apr 26 1863. I visited Adm. Porter aboard the Benton. It is his opinion that the Rebel fortifications at Grand Gulf are strong and getting stronger. We must attack soon. I went straight to Gen. McClernand at Mrs. Perkin’s plantation. McClernand wanted to wait to launch an attack until his entire corps was present. I told him time was of the essence and to immediately load both of his divisions that were at the plantation onto the waiting transports.
