As crews were cleaning up tools & apparatus from the soggy MVC back at the station, Sussex EOC transmitted the box assignment at 18:14 for a reported working residential structure fire at in the area of Medic Station 103 on Dagsboro Rd. On the box was the DVFD, Millsboro VFC & SCEMS 103. EMS 25 who was at Medic Station 103 reported a 2 1/2 story Cape Cod w/ hvy fire venting from side "C" & possible subjects trapped. With members being at the station at time of dispatch, Engine 731, Engine/Tanker 73, Rescue Co. 73 & Tanker 73 all arrived on scene at 18:20 to find as reported w/ Chief Glenn as IC. Engine 731 continued down Coffin Ln (dirt) laying 5" LDH, while all other units staged on Dagsboro Rd. Crews from the Engine/Tanker & Rescue Co. gathered hand tools & walked back to the scene moving the LDH to the side to allow access by other units. The crew from Engine 1 pulled a 2" line and began hitting the fire on Side "C", While the crews from the Engine/Tanker & Rescue Co. pulled two 1 3/4" lines, 1 line to side "B" & 1 line to back up the crew on the 2". With the arrival of Engine 831 additional lines were stretched another 1 3/4" & a 2 1/2". Crews were ordered not to enter the structure by IC due to the roof on side "C" had already failed. IC requested 2 additional Engine companies to the scene & 2 to fill the DVFD. With hvy rain & 30 mph winds & gusts to 45 crews went to work knocking the fire. After the baulk of the fire was knocked, crews entered the residence & began to mop up & overhaul. Crews were able to save 2 large exotic fish from the 1st flr rear living room. Crews from Dagsboro, Millsboro, Frankford, Millville, Roxana & SCEMS operated for 3 1/2 hrs. before returning to service. Crews from Gumboro & Selbyville covered the district during the incident, running an additional structure fire in Dagsboro at Mediacom Cable. This turned out to be burnt popcorn.
