[SOLVED] Sitecore 6 - Unable to remove master database on Content Delivery Servers

I'm having a bit of a problem with our Content Delivery servers. We are unable to remove the master database without it blowing up. Our current information is below:

Sitecore.NET 6.5.0 (rev. 111230)
December 30, 2011
.NET Framework 4.0.30319.239
Database version: 500

The error and stack trace that we are receiving is:

[InvalidOperationException: Unknown connection string. Name: 'master']
   Sitecore.Configuration.Settings.GetConnectionString(String connectionStringName) +364
   Sitecore.Configuration.Factory.CreateFromConnectionStringName(XmlNode configNode, String[] parameters, Boolean assert) +106

It appears that when the History Manager is initializing it is requesting information from the master database at some point.

After adding SwitchMasterToWeb.config to the app_config/include folder I now get this message:
