Context: On 2 July Lord John Russell, 1st Earl of Bedford's initial force had reached Honiton. It included 160 Italian arquebusiers and a thousand landsknechts, German footsoldiers, under the command of Lord William Grey. With promised reinforcements from Wiltshire and Gloucestershire, Russell would have more than 8,600 men, including a cavalry force of 850 men, all of them well armed and well trained. Russell had estimated the combined rebel forces from Cornwall and Devon at only 7,000 men. On 28 July Arundell decided to block their approach to Exeter at Fenny Bridges. The result of this conflict was inconclusive and around 300 on each side were reported to have died with Lord Russell and his army returning to Honiton.

Question: How many more men did Russell's force have?

Answer:
1600
