is an 1881 oil painting by Lady Butler depicting the start of the charge of the Royal Scots Greys, a British heavy cavalry regiment that charged with other British heavy cavalry at the Battle of Waterloo in 1815.

The painting has been reproduced many times and is considered an iconic representation of the battle itself, and of heroism more generally.

[1] In reality however, it appears that the Scots Greys did not start the charge at a gallop, due to the broken ground, and instead advanced at a quick walk.

The title comes from the battle cry of the soldiers—the Greys called "Now, my boys, Scotland forever!"

In 1888 Colonel Thomas Walter Harding donated the painting to Leeds Art Gallery.
