You have the Knight that can be used? And the LB was recently moved. There is also a river between the LB/WE and Delhi for a little added bonus defense.As long as Gandhi is not threatening our cities or improvements we should continue the war. Not sure how we can capture the worker since he can only be captured by a unit that is moved right next to him. Anyway, I can try. Perhaps I should move the LB and WE away from Delhi to avoid an attack from the Musketman. Unsure if the LB has been fortified where he is now - it looks like he's not fortified.

Here is CP's suggestion:
CP said:Since G is conveniently moving his cat out of Delhi, we may have the option of capturing the worker before he finishes pasturing the cows. Need to move our lb and WE away from cat this turn (but not threatening the worker); move knight 1S next turn and then SSW the following turn (don't think the cat will attack him), then put all three of our units on the silk 2S of Delhi the following turn (with the explorer within range of the cows as well); then we can decide on the ensuing turn whether the worker is worth the potential cost in units. One potential benefit of a successful attack might be G's willingness to trade Gunpowder for peace. Along this line, we might also consider researching a small part of the way to Gunpowder to facilitate that peace trade.
