It's not a lost case for Germans even if the Bridge No 4 falls. The bleed will continue until the Amis cap either the Farm or FJR6 position and a teamwork defense can hold them even if it is difficult.
Of course, people have the tendency to spawn on one or the other. In addition, they often make the fatal mistake by assuming that any backcappers flanking behind the fence and through the ditch in the northwest (or southeast IRL, but let's not confuse people) would always go for the FJR6 flag - no they don't always, sometimes they do go for the Farm instead, attacking it from the lightly defended north/east side so having a forward-only defense of the Farm (the river and the MG nests) will result in a besieged German position on FJR6 that gets overrun more often than not, putting the Germans on bleed.
