What are the connotations of this comic?

I saw this comic titled:

"A cartoon published in Britain on 12 August 1914. The cartoon is entitled ‘Bravo, Belgium!’ The boy guarding the gate represents Belgium."

What are the connotations of this comic?

Just so you know, your link doesn't work - Gutenberg doesn't allow linking to their images. I imagine your comic has something to do with British support of Belgium's decision not to give the German Army passage through Belgium to attack France, but without the image it's going to be hard for anyone to give you a solid answer.
