O captain my captain

"Whitman and Lincoln shared the national stage in Washington DC during the Civil War. Though the two men never met Whitman would often see Lincoln’s carriage on the road. The president was never far from the poet’s mind and Lincoln’s “grace under pressure” was something Whitman returned to again and again in his poetry. Whitman witnessed Lincoln’s second inauguration and mourned along with America as Lincoln’s funeral train wound its way across the landscape to his final resting place."--Amazon.com.
