Like, for example, pulling a trailer up a hill. The ability of the engine to keep turning the wheels under load is torque. The more torque an engine has, the heavier the trailer and the steeper the hill it will be able to negotiate.
Horsepower simply defines how fast an engine can accelerate under normal conditions. A small amount of torque will be needed to move it off from standstill and more will be required for a hill start, but once you're moving, any load effectively dissipates almost completely and it is just the engines ability to produce raw power which is important.
