Gaines' Mill | June 27, 1862 | 7:00 - 8:00 pm

Around dusk, Gen. Robert E. Lee ordered an all-out attack all along the Confederate line, which now included the division of Maj. Gen. James Longstreet on the right. Lee ordered forward around 32,000 men in 16 brigades, his largest attack of the war. They moved forward individually rather than in one solid blow; some were repulsed in small unit actions. Porter had around 34,000 men, including reinforcements, and had many more artillery batteries than the Rebels. The first Confederates to pierce the Federal line were the Texas regiments of Brig. Gen. John B. Hood along Boatswain’s Creek. As night fell, Porter’s men fell back south of the Chickahominy River.
