5,000 effective infantrymen available to extend his lines. March 28, 1865 Grant, Sherman, and Lincoln, joined by Rear Admiral David Dixon Porter, met again on the River Queen. The generals outlined their strategies and told Lincoln they anticipated the need for one more campaign, although Lincoln expressed his hope that much further bloodshed could be avoided. This was the only conference at which Lincoln conferred with his top military officers about post-war policies. Admiral Porter made notes that night in which he recorded that Lincoln wanted the Confederates to be let go and treated liberally. Porter quoted Lincoln as saying that his only desire was for "those people to return to their allegiance to the Union and submit to the laws." Lincoln also indicated that he did not want the generals making political settlements with the Confederates. On the night of March 25, Major General Edward Ord quietly moved units from the Union Army of the James, including two divisions of Major General John Gibbon's XXIV Corps, a division of Major General Godfrey Weitzel's XXV Corps and Brigadier General Ranald S. Mackenzie's cavalry division from the Richmond lines to fill in the Petersburg lines when the II Corps moved out of them to support Sheridan. Confederate Lieutenant General James Longstreet's corps defending the Richmond lines failed to detect the movement of Ord's men, which held Lee back from moving some of Longstreet's forces to defend against the movement of Grant's forces. Ord's men began their march on March 27–28 and arrived near Hatcher's Run to take the positions occupied by the II Corps on the morning of March 29. Brigadier General Ranald Mackenzie's cavalry division from the Army of the James joined Sheridan on March 28. On the night of March 28, 1865, Grant modified his order, telling Sheridan to lead his troopers around the Confederate right flank and to fight the Confederates, with infantry support, if the Confederates came out of their trenches. Otherwise, Sheridan was to wreck the railroads as much as possible and again was told, at his discretion, that he could return to the Petersburg lines or join Sherman in North Carolina. Sheridan was told to move first to the rear of the V Corps and around their left flank to Dinwiddie Court House in an effort to outflank the Confederates and cut the Boydton Plank Road. Grant ordered Warren's V Corps to outflank Lee's line
