It didn't take long for the Bosnian Muslims to realize that the UN was in no position to live up to its promise to "protect" Srebrenica. With some help from outsiders, they began to infiltrate thousands of fighters and weapons into the safe haven. As the Bosnian Muslim fighters became better equipped and trained, they started to venture outside Srebrenica, burning Serb villages and killing their occupants before quickly withdrawing to the security provided by the UN's safe haven. These attacks reached a crescendo in 1994 and carried on into early 1995 after the Canadian infantry company that had been there for a year was replaced by a larger Dutch contingent. Lewis MacKenzie
