This is from Jacob's Ladder, and the full quote is: "They served their country, their God, and many children with all they had. May we here do the same." Another way of saying "May we here do the same" in a context like this is "If fate allows it, I hope that we are able to do the same here." To paraphrase the entire quote's structure, it's "<Somebody> did <something, somewhere>. Let's try and do the same thing here." By the way, questions like this are easier to answer if plenty of context is available. Providing that context for folks answering the question saves them the trouble of doing the research. :)
